Ticket #18340 – Description
v4 v15 1 The following will eat all your memory: 2 {{{ 3 $ ( ulimit -s unlimited; ./sage -t --long src/sage/schemes/elliptic_curves/lseries_ell.py ) 4 }}} 5 This sets the stack size to "unlimited". The `gp` process which is executed by this doctest will then use a very large amount of memory. 6 7 This happens in particular with GNU `make` < 3.82 due to [https://savannah.gnu.org/bugs/?22010] 8 9 ---------- 10 1 11 See https://groups.google.com/d/topic/sage-devel/ydDfHsCxpAc/discussion 2 12 3 13 (Older) Thread on sage-release: [http://thread.gmane.org/gmane.comp.mathematics.sage.release/2757] 4 ----5 6 Work-around I currently use (with `bash`):7 {{{8 $ (ulimit -v 4000000; make ptestlong) # e.g.; limits virtual memory9 # of *each* (sub)process to ~4GB10 }}}11 Interestingly, all test pass despite the greedy `gp` process getting killed.
