I've tried to get GDB stacktrace but after native stacktrace, I can't get GDB
to work. So I've launched my app from withing gdb, setting all signal handlers
as mentioned on http://www.mono-project.com/Debugging#Debugging_with_GDB, and
this is the stacktrace that I've managed to collect. It doesn't occur in
mono_array_new_specific but rather in mono_string_new_size, but maybe it'will
be useful. 

GDB stacktrace:
