Well, you can man 3 signal, and set a handler which aborts for
everyone of them. They're likely to happen a lot though, so you
probably want to enable your signal handler just before the blit
you are talking about, and then only log them in a memory buffer
and restore the old signal handlers after the blit is done.
You can also try to set a memory write breakpoint on errno, but
I haven't tried that ever. GDB might be able to do that, I kind
of remember seeing a reference to that somewhere...
