Example code.


We got the bug with pointers on latest Mono compiler on MacOSX.
I will show simple example:


struct MyStructure
    int q;
    int z;
    int a;

MyStructure* pointer2 = ...;

pointer2 += 10;


On the Mac this works like: pointer2++;
This increase only 12 bytes (size of structure). Need 120 bytes.
if make "pointer2 += 20", then increased 12 bytes too.

See attached file for compilable source.
