Data about the code to reproduce the stack corruption

Ok.... in attach is the code to reproduce the stack corruption in ARM arch

mono version:

Mono JIT compiler version 20080529 (tarball)

        GC:            Included Boehm (with typed GC)                           
        SIGSEGV:       normal

        Architecture:  arm                                                      
        Disabled:      none 

the test code gives this results:

On 8x86(GOOD!!) ->  Values LNAR2.1, LNAO3.2 MSGCODE1

on Arm: (BAD!!! STACK Corrupted) ->Values LNAR3.2, LNAO0.0 MSGCODE1
