This seems to have been fixed, since with the latest from gcc/svn, git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk <at> 186106 138bc75d-0d04-0410-961f-82ee72b054a4 I can now bootstrap the latest emacs.

From: Jim Meyering <jim <at> meyering.net> To: bug-emacs <at> gnu.org, bug-gcc <at> gnu.org Subject: temacs segfaults w/MALLOC_PERTURB_!=0 when compiling with gcc-4.8.0 Date: Sun, 01 Apr 2012 11:25:02 +0200I bootstrap emacs from bzr every two or three days, using whatever gcc happens to be in my PATH. The last successful build/install was on March 28th. However, as far as I can see, the new problem is coming from the tools I'm using, and not from emacs, since attempting to build that previously-succeeding commit now evokes a segfault. It's easy to paper over the problem. My (failing) build procedure does this to cancel the effect of my always-set MALLOC_CHECK_ envvar: make bootstrap RUN_TEMACS='MALLOC_CHECK_=0 ./temacs' also making it turn off MALLOC_PERTURB_ works around the immediate problem. With this, the build completes normally: make bootstrap RUN_TEMACS='MALLOC_PERTURB_=0 MALLOC_CHECK_=0 ./temacs' But that probably just masks the real problem. This is happening on an x86_64 F17 system, when I use built-from-svn gcc-4.8.0 20120327 or newer (confirmed segfault also with today's 4.8.0 20120401). However, using the stock gcc, (aka gcc-4.7.0-1.fc17.x86_64), there is no problem. Using valgrind the problem does not arise. Same story when using gdb directly, so below I let it generate a core file and ran gdb on that. It suggests that alloc.c's mark_object is dereferencing a freed pointer, due to the pattern of 0x22 bytes scribbled into the pointer: #0 mark_object (arg=<optimized out>) at /h/j/w/co/emacs/trunk/src/alloc.c:5616 5616 if (ptr->gcmarkbit) (gdb) p *ptr Cannot access memory at address 0x2222222222222220 I.e., to reproduce this failure, you would run this: ./configure CC=/path-to-gcc-4.8.0/bin \ && env MALLOC_PERTURB_=88 \ make bootstrap RUN_TEMACS='MALLOC_CHECK_=0 ./temacs' If no one beats me to it, later in the week I'll bisect gcc until I find the commit that changes whether ./temacs segfaults.
