I found a call stack corruption when calling a method of a class that is inside
of a external assembly.
I think that the runtime undercalculates the stack size required...
In mono on 8x86 the same assemblies work perfectly!!

the simptom is like this:

class a1


  structtest a,b;
  externaclass.methodtest(a, b);

class externaclass
  methodtest(structtest parm1, structtest parm2)
     // inside of this the parm1 value is swapped with the value of parm2

if the call stack its a bit more deeper before calling the external assembly
method the first value is completly corrupted -> its 0

i think that this is an undercalculation for the stack required....

thanks in advance
