Could you compile it with -fsanitize=undefined and see if anything pops up? Also many bugs were already fixed on the gcc-5 branch. Please try a newer gcc snapshot. (In reply to octoploid from comment #1) > Could you compile it with -fsanitize=undefined and see if anything pops up? The strange thing, it works, as well as when compiled with gcc-6.0.0-alpha20150531 without this option. Thanks, Helmut doesn't really seem to be a game bug to me. Same here with gcc-5.2.0 and -fsanitize=undefined.

PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, USE_PYTHON if you build with -O2 -fno-builtin, does it work ? it's a bug in gnubg. their common.h does: #if !_GNU_SOURCE && !defined (__attribute__) #define __attribute__(X) #endif and then it proceeds to include glibc headers. since glibc relies on gcc attributes, things start to fall down quickly. specifically, the problem here is that w/newer gcc defaulting to a newer C standard where the behavior of "static inline" has changed. glibc would use __attribute__((gnu_inline)) on the string functions to get the correct behavior, but gnubg has broken that. that leads to copying.c including string.h which ends up including local dummy copies of the string functions (like memset). so when gnubg starts up, glibc and such libraries call memset which is the dummy call in gnubg which calls itself thus getting stuck. i e-mailed upstream and cc-ed people in that older thread (although for some reason my e-mail isn't showing up in the archive) in the mean time, i committed this hack: http://gitweb.gentoo.org/repo/gentoo.git/commit/?id=e121815fa352616db9031e5c366065c577795b22 |
When using gcc-5.1.0 to build games-board/gnubg strange effects occur. - When compiles with -O2 (my standard setting), gnubg goes in to a loop (in memset) *before* function main is entered. - when compiled with -O1 it gets a segment fault in memset *before* function main is entered. -when compiled with -O0 it works. Compileing gnubg with -O3 and gcc-4.9.2, everything is OK. Note, I have recompiled most parts of my system (including glibc) with gcc-5.1.0 during the last weeks. Many thanks for some hints, Helmut emerge --info games-board/gnubg Portage 2.2.20 (python 3.4.3-final-0, default/linux/amd64/13.0/desktop, gcc-5.1.0, glibc-2.20-r2, 4.1.0-rc7 x86_64)
