[Mono-list] mcs 2.10.2 compiles fine, gmcs crashes

[Tim Nelson]

I have a simple Helloworld console app that compiles fine with mcs,
but gmcs crashes with:


Unknown errno: Bad address

WriteFile returned 31

Stacktrace:

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.
