Source: pygalmesh Followup-For: Bug #928140 Not a regression as such: 0.2.6-1 also exhausts memory on i386 sometimes (not always), cf. https://tests.reproducible-builds.org/debian/logs/unstable/i386/pygalmesh_0.2.6-1.build2.log.gz
This is a general problem with meshing libraries. mshr has a similar problem on i386, https://bitbucket.org/fenics-project/mshr/issues/89/ I spoke with upstream about it, he said the reason will be cgal's heavy use of c++ templates. No easy way around it. Building with -g -O1 (or -O2 without -g) helps mshr, we can test if it helps pygalmesh too. Drew
