David,

I didn't actually use gdb, but fetched the crash log from the logs folder:

Exception Type:  EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000

The '_chk' stuff is because I use -D_FORTIFY_SOURCE=2.  I suspect a buffer overrun involving strncat().

(I had not turned fortify on before, which explains why my previous test worked.)
