GuardMalloc SIGTRAP

Hi
I'm trying to debug some memory issues and have enabled GuardMalloc.
It properly triggers a break saying in the gdb console:

GuardMalloc[luaAV-1368]: Tried to free pointer at 0x59c000 which is
not currently a pointer to a malloc buffer.
GuardMalloc[luaAV-1368]: Explicitly trapping into debugger!!!
Program received signal:  "SIGTRAP".
(gdb)

but when I go to type a command like backtrace into the command line,
it doesn't execute the command.  It just goes to the next line as if I
were in a text editor.  How can I get around this behavior?

I'm on Tiger with xcode 2.4.1

thanks,
wes
