Comment (by simonmar):
Strange, it appears to be failing at the inline assembly
{{{
#if i386_HOST_ARCH || x86_64_HOST_ARCH
__asm__ __volatile__ (
"lock/cmpxchg %3,%1"
:"=a"(o), "=m" (*(volatile unsigned int *)p)
:"0" (o), "r" (n));
return o;
}}}
but since this is an i386 processor, I don't see why it shouldn't let you
execute that instruction. Perhaps you could disassemble the instruction
that causes the crash, and see if it looks plausible?
Incedentally, your workaround will probably lead to problems later,
because it'll default to a non-atomic cas() implementation.
