Compiling revision 13634 against GCC 4.8.1 on SUSE10 with CFLAGS="-O3 -g0"
causes the valgrind executable to crash with a SEGFAULT. Attaching with GDB
shows
Program received signal SIGSEGV, Segmentation fault.
0x000000003805ab5a in vgPlain_memset ()
(gdb) up
#1 0x000000003805ab5f in vgPlain_memset ()
(gdb) up
#2 0x000000003805ab5f in vgPlain_memset ()
(gdb) up
...
which looks very similar to this
http://llvm.org/bugs/show_bug.cgi?id=9795
but rebuilding with CFLAGS="-O3 -g0 -ffreestanding" did not help the
situation.
Debug builds work fine. -O2 works fine as well.
