Hmm, I'd expect memcpy() of length zero to be fine even if src/dst were
null.
memcpy is fine, the segfault happens at line 713 two lines below where :
pstip->state.samplers[i] = NULL;
OK, maybe it's pstip that's null then.
I asked gdb what to print pstip->state.samplers[0] and it told me
something like "unavailable".
Yeah, you'll need a debug build to get useful info out of gdb (configure
with CFLAGS="-g -O0").
Can you try this patch?
I can and I will.
That's probably not it, given the above. Can you try setting a
breakpoint on pstip_destroy() and see if that's getting called before
the segfault? If so, things are getting freed in the wrong order.
