Description of Problem:

There seem to be a bug on mono_test_marshal_amd64_pass_return_struct2 that
makes the pinvoke2.cs test not pass. It happends on i386 only. On amd64 it
passes ok.

Steps to reproduce the problem:
1. Get the latest mono with svn co http://bsd-sharp.googlecode.com/svn/trunk
bsd-sharp
2. cd bsd-sharp/lang/mono; make tests
Patches applied are on the files/ subdirectory.


Actual Results:

Expected Results:
In line 1037 of pinvoke2.cs, s2.i should be 6 and s2.j should be 4.
Their values are 6 and -1077943496.

How often does this happen?

Additional Information:

Maybe this has something to do with
http://anonsvn.mono-project.com/viewvc/trunk/mono/mono/mini/decompose.c?view=log&pathrev=123706

(This is 2.4 RC1)

If you need additional information, just tell!
Thanks.
