Public bug reported:
If I run command
/usr/bin/dmcs /noconfig "/out:Test.exe"
"/r:/usr/lib/mono/4.0/System.dll" "/r:/usr/lib/mono/4.0/System.Core.dll"
/nologo /warn:4 /debug:+ /debug:full /optimize- /codepage:utf8
/platform:x86 "/define:DEBUG" /t:exe Main.cs
with the attached Main.cs I get
Internal compiler error at Main.cs(8,36):: exception caught while
emitting MethodBuilder [MainClass::Main]
Unhandled Exception: System.ArgumentNullException: Argument cannot be null.
