The error message comes from 'g_thread_abort', which calls 'abort'.  The 
reason there was no backtrace is exactly what I said.  I know that's the 
case because I removed the "@" at the beginning of the Makefile rule so 
that the command would get echoed, but it didn't get echoed in the 
compilation above (and others like it).  On the other hand, it did get 
echoed in the SIGSEGV examples that I mentioned in my previous mail.
