[Valgrind-users] Fwd: 3.9.0-SVN optimized build crashes with infinite loop

[Gregory C. <gcf...@gm...>]

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

but rebuilding with CFLAGS="-O3 -g0 -ffreestanding" did not help the
situation.

Debug builds work fine. -O2 works fine as well.
