Geoff,

Thanks, here you go:

To me, this doesn't look like JIT'ed code with all those weird .long values.

(gdb) bt
#0  0x000000010078d1b0 in ?? ()
#1  0x00000001000aea04 in create_exception_two_strings (klass=0x100832b58,

#5  0x00000001000017c4 in start ()

In the backtrace I notice that mono_runtime_invoke is not mentioned, but
according to my printfs it does not return from there - does this indicate
stack corruption?
