Sample attached and output attached.

Running:
mcs -target:library PreProcess.cs
mcs RunInOtherDomain.cs
mono RunInOtherDomain.exe

This does not always fail.  You may have to run the exe a few times.

Observations:
This was found on recent svn built versions of mono on Windows and SUSE
10.2.  A regression from 1.2.
Removing or changing the argument type of CreateAdditionalFiles will succeed.
Changing line 79 in RunInOtherDomain.cs to false causes the Invoke call to
be run in the current AppDomain and the error does not occur.
Compiling PreProcessor.CreateAdditionalFiles into the exe works fine. 
(uncomment ln 52 in RunInOtherDomain.cs  and run mcs RunInOtherDomain.cs
PreProcess.cs)

mono_marshal_get_runtime_invoke () is allocating the
signature from the method's class image.

Since this image is unloaded with the appdomain (the main assembly
has no reference to this image), corlib's runtime_invoke_cache
contains a method whose sig is now garbage.
