Summary: Crash after AsyncCallback to Socket.BeginReceiveFrom
Classification: Mono
Product: MonoTouch
Version: unspecified
Platform: Other
OS/Version: Other
Status: NEW
Severity: Blocker
Priority: P5 - None
Component: Class Libraries
AssignedTo: mono-bugs at lists.ximian.com
ReportedBy: ed at anuff.com
QAContact: mono-bugs at lists.ximian.com

I'm having a crash with MonoTouch 1.1 that wasn't happening with 1.03.
No changes in my code other that to recompile with 1.1, and if I
reinstall 1.03, my app works again without any problems.
Compiling with --nolink resolves the problem.
A call is made to a udp socket with Socket.BeginReceiveFrom. The AsyncCallback
passed to Socket.BeginReceiveFrom is called and completes without problem but
after the callback returns the crash occurs. This is on the first packet being
received.
I am unable to carve out a simple repro, if this information isn't sufficient
for figuring out why it's happening, I will need to provide my project along
with login credentials for the tester. I'm not sure how to add a private
upload to bugzilla.
