Can anybody confirm this? I've tried it on different machines with Win95,
WinNT 3.51 and WinNT 4 (sp3) and I didn't encounter this situation.
If this happens on your machine, please send me a description of your
hardware. I'm particular interested in the OS (95, NT3 or NT4 the language
version you use and the SPs (on Win95 the OSRel) installed).

The oop pointer might still be ok (you can only check this by testing if
memory < oop < endOfMemory) but the oopsize is definitely to large.

If this is the case, then I suspect that some object header is wrong.
It would explain why the VM crashes on save but I can save the "original"
1.3 image nevertheless.
