As I know, gdb is no more present in Mac. I think it was substituted by lldb. Anyway, on gdb what is the correct syntax in order to launch your external?
you cannot "launch" an external. anyhow:
on linu x i use: $ gdb --args pd -stderr -nrt -nosound -lib /path/to/external test.pd (gdb) run [...run-until-crash...] (gdb) bt
on OSX you need to specify the full path to the actual Pd-binary . the important Pd-flags are: "-nrt" (if you don't want to clutter your gdb console with "pd-watchdog: signalling...") and "-stderr" (in case you print something important before the crash)

PS: btw, check your args and the return value (or rather: whether the offset of the t_int* is correct) in the perform routine.
