--- Comment #4 from Christophe Prud'homme <christophe.prudhomme at feelpp dot org> 2012-08-05 22:37:57 UTC --- The code I attached to this bug report seems to be fine now. However I have other instances of these crashes(segfaults) in other codes that I will attach any time soon. The diagnostic is the same : - crash (segfault) with -O1 -O2 and -O3 - ok in debug mode - ok with gcc46, gcc45 and clang31
