That's the output of the test case(compile it with gmcs, not mcs):

Creating dummy
--- structure.test should be null ---

  at (wrapper managed-to-native) object.wrapper_native_(nil) () <0x00042>
  at (wrapper managed-to-native) object.wrapper_native_(nil) () <0xffffffff>
  at TestStructToPtr.MainClass.Main (string[]) <0x0007a>
  at (wrapper runtime-invoke)
(object,intptr,intptr,intptr) <0xffffffff>

Native stacktrace:

        mono [0x4bd937]
        mono [0x520a00]
        mono [0x421c91]

Debug info from gdb:

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