Subject: Use a smaller stack for stack-overflow test.
X-Git-Tag: v3_11~215^2
X-Git-Url: http://info.iut-bm.univ-fcomte.fr/pub/gitweb/simgrid.git/commitdiff_plain/53f94d305342966b29fe32f1d397071a22c16417?hp=9a74a4d9c970bf6b49d2c15d284ca190451d5ef6;ds=sidebyside

Use a smaller stack for stack-overflow test.

It is needed on FreeBSD to have a stack size < 125K to generate a SIGSEGV with
SEGV_ACCERR when using threads, and to have this test succeed.
Without that, the SIGSEGV is correctly generated, but with SEGV_MAPERR, and the
error message is not displayed.

I don't fully understand what's going on.
