[Mono-list] Thread Crashes

[Stefan Bühlmann]

I do not have a native backtrace but:


* Assertion at wait.c:230, condition `thr_ret == 0' not met

Stacktrace:

  at <unknown> <0xffffffff>
  at (wrapper managed-to-native) System.Threading.Thread.Thread_internal
(System.Threading.Thread,System.MulticastDelegate) <0xffffffff>
  at System.Threading.Thread.Start () <0x001a7>
  at test.MainClass.Main (string[]) <0x00199>
  at (wrapper runtime-invoke) <Module>.runtime_invoke_void_object
(object,intptr,intptr,intptr) <0xffffffff>

=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
