From: Danny Smith <dannysmith@clear.net.nz> To: gcc-gnats@gcc.gnu.org Cc: Subject: Re: c++/8047: [i386] Stack corruption with exceptions Date: Mon, 18 Nov 2002 23:51:15 +0000 [The following observations are for mingw32 and cygwin builds with Dwarf2 EH enabled. The patches to enable Dwarf2 are in the cygwin-mingw-gcc-3_2-branch.] I have just tried this with i386-mingw32 (GCC3.3) with same result: Okay with march=i686, stack exhaustion with i[345]86. However, if add -maccumulate-ougoing-args, the stack is okay with default -march=i386 Ditto with cygwin Coincidentally, in mingw and cygwin, functions that call a __stdcall function (callee pops stack) show stack corruption with Dwarf2 exceptions when compiled with -fomit-frame-pointer, but are okay with -fomit-frame-pointer -maccumulate-outgoing-args. Also, perhaps related is PR6764, which still fails on mingw with --march=i386 but not with -march=i686 or -maccumulate-outgoing-args Danny
