[Mono-list] Mono process dies with "trace trap"

Ok, I have never done any debugging using GDB, so I'm pretty lost here.

The page tells me to use a function called "print_method_from_ip", when I do it in a gdb session:

(gdb) p print_method_from_ip(0x03f83f1e)
No symbol "print_method_from_ip" in current context.


How do I load these mono functions to my GDB session?

The app is being loaded as:

gdb --args mono Sync.Mac.Cli.exe

Then I hit "run" and then I wait until the program crashes.
