(Mathematical note, through trying to find a smaller example, I am noticing that E_{8}^{(1)} is special in that it is the only place where I see nonfulldimensional nonempty polytopes in my computations. Well, I also see a 0dimensional polytope for type D_{4}^{(3)}, but that doesn't cause a crash as it is likely specialcased.)
Also can you update the comment before enableflint
to also say you enable flint as it is part of the standard packages of Sage?

comment:14 Changed 3 years ago by
I can confirm this crash. Here on Mac OS X, this actually becomes an unhandled SIGABRT:
Assertion failed: ((int) rank()==n), function LLL_red, file ./libnormaliz/matrix.cpp, line 2901.  0 signals.so 0x000000010af572d8 print_backtrace + 40 1 ??? 0x000000010dcac1e0 0x0 + 4526359008  Unhandled SIGABRT: An abort() occurred. This probably occurred because a *compiled* module has a bug in it and is not properly wrapped with sig_on(), sig_off(). Python will now terminate.

I confirm that the packages build and pass selftests and doctests correctly on both 64 and 32 bit architectures on Debian stretch. I also comfirm that there is a crash on both architectures regarding the test provided by Travis (which should be added in our doctests, once the issue is fixed).
comment:17 Changed 3 years ago by
I am not sure what the matrix ieqs represents. My interpretation: inhomogeneous inequalities, and we want to compute the lattice points in the polytope they define. Under this assumption I have made a Normaliz input file rash.in
amb_space auto inhom_inequalities [[0, 2, 0, 1, 0, 0, 0, 0, 0], ... [0, 0, 0, 0, 0, 0, 0, 0, 1]] HilbertBasis
Then a run of
normaliz c crash.in
finishes without any problems in 3.5.1 and the intended 3.5.2. It turns out that the polytope is empty:
0 module generators 1252 Hilbert basis elements of recession monoid 0 vertices of polyhedron 39 extreme rays of recession cone 11 support hyperplanes of polyhedron (homogenized) embedding dimension = 9 affine dimension of the polyhedron = 1 rank of recession monoid = 8 ...
Is my interpretation of the input correct?
comment:18 Changed 3 years ago by
Of course, if the matrix represents inhomogeneous inequalities, what is the RHS? My input above assumes it is the last coordinate. I will now try with the first.
comment:19 Changed 3 years ago by
Unfortunately Normaliz crashes when coordinate 1 is interpreted as the RHS. Will take care of it.
comment:20 followup: ↓ 21 Changed 3 years ago by
The problem is solved. Replace line 323 of source/libnormaliz/sublattice_representation.h
by
if(Vertices.nr_of_rows()==0  Vertices.rank()<EmbDim){ // use Supps for LLL coordinates
i.e., delete "1" in this line.

Great, thank you for figuring it out. I am guessing you are in the process of making a commit upstream or should I do a pull request?

I've pushed a branch with a fix for this problem. However, I have now come across another crash:
sage: RC = RiggedConfigurations(['E',8,1], [[4,2]]) sage: len(RC.module_generators) python2: ./libnormaliz/project_and_lift.cpp:75: std::vector<long unsigned int> libnormaliz::ProjectAndLift<IntegerPL, IntegerRet>::order_supps(const libnormaliz::Matrix<Integer>&) [with IntegerPL = long long int; IntegerRet = long long int]: Assertion `Supps.nr_of_rows()>0' failed. 
I have verified that this did at least not crash before (well, up to my patience level of 2 minutes).
However, much more worrying is this:
sage: RC = RiggedConfigurations(['E',8,1], [[5,2]]) sage: %time len(RC.module_generators) CPU times: user 25 s, sys: 52 ms, total: 25 s Wall time: 6.95 s 6009
versus before
sage: RC = RiggedConfigurations(['E',8,1], [[5,2]]) sage: %time len(RC.module_generators) CPU times: user 1min 11s, sys: 320 ms, total: 1min 11s Wall time: 14.6 s 7066
Although the [5,1]
example both returns 75.
I will extract the polytopes and find out which one gives a different number of lattice points. Give me a few minutes.
New commits:
f9f17a4  Added patch to fix upstream issue #176.

A hint: If you use P = Polyhedron(ieqs=ieqs, backend='normaliz', verbose=True)
, the PyNormaliz

I wasn't aware of that, thank you. Although it does not yield much more information on the new crash:

PS  That means the docstring for Polyhedron
needs a minor adjustment:
 ``verbose``  boolean (default: ``False``). Whether to print verbose output for debugging purposes. Only supported by the cdd backends.

The wrong number of lattice points is a more severe problem. I don't have an explanation for it.
The (first and solved) problem in sublattice_representation.h has nothing to do with it. After the change in sublattice_representation.h:323 a second problem has become visible there in Normaliz' own tests. One must change line 325 to
if(SuppHelp.rank()<EmbDim1)
But againthis has nothing to do with the wrong number of lattice points.

I am afraid all I can do is give you examples from my usecase as I do not understand too much about how Normaliz works. Thank you for your continued efforts and quick responses.

I added that to the patch, but (as you might be aware) I am now getting yet another crash with the same example as in comment:25:

comment:34 Changed 3 years ago by
The problem with the wrong number of lattice points (or a failing assertion) was not caused by a severe problem, but by a silly bug. As a temporary fix I suggest to include as lines cone.cpp:3804 and 3805
if(!is_parallelotope) Pair.clear();
So with some surrounding the code there should be
is_Computed.set(ConeProperty::IsPointed); } } if(!is_parallelotope) Pair.clear(); if(!inhomogeneous && !isComputed(ConeProperty::Grading)) return;
I plan to release 3.5.2 at the end of this week. It will contain a more conceptual solution.
Please test.

and the >2x speedup is very impressive. :) I've updated the patch accordingly.
@mkoeppe Perhaps we should just wait on this upgrade until 3.5.2 is released to avoid the patch since it will be in just a few days?
As far as adding tests go, I think we should explicitly add the polytopes mentioned above rather than the RC code. They are isolated and much faster to test.

It can be on a separate ticket, but the docstring for verbose
should also say it is supported for the normaliz backend as well.
