[MonoTouch] App crash on release to device but is Ok on debug and simulator

[Sebastien Pouliot]

Hello Karl,

You should first compare the project options (e.g. defines) between
your Debug and Release configurations. One might have received updates
(e.g. Debug) when developing while the other (e.g. Release) could have
bitrotten a bit.

Next the crash includes everything about the crash but sometimes lacks
the pre-condition(s) that triggered it.

a) start a terminal window
b) execute the following command: "/Developer/MonoTouch/usr/bin/mtouch
--logdev" (without the quotes)
c) start your application of the device and make it crash
d) copy/paste the console log into your reply email (or better a bug report).


Regards,
Sebastien
