Status in “mono” package in Ubuntu:
  New

Bug description:
  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]
