  • Ticket #18340

    • Property Cc jdemeyer added
    • Property Component changed from PLEASE CHANGE to packages: standard
    • Property Summary changed from Memory issues while testing (gp process) to If given unlimited stack, gp uses it all

  • Ticket #18340 – Description

    v4 v15  
     1The following will eat all your memory:
     2{{{
     3$ ( ulimit -s unlimited; ./sage -t --long src/sage/schemes/elliptic_curves/lseries_ell.py )
     4}}}
     5This sets the stack size to "unlimited". The `gp` process which is executed by this doctest will then use a very large amount of memory.

     7This happens in particular with GNU `make` < 3.82 due to [https://savannah.gnu.org/bugs/?22010]

    6 Work-around I currently use (with `bash`):
    7 {{{
    8 $ (ulimit -v 4000000; make ptestlong)  # e.g.; limits virtual memory
    9                                        # of *each* (sub)process to ~4GB
    10 }}}
    11 Interestingly, all test pass despite the greedy `gp` process getting killed.
