At first I would like to thank you for testing...

Can you please tell me which compiler version have you used (output of 
"gcc -v" and "ld --version")?

I'll try these systems myself sometimes soon...I know pretty much 
nothing works ATM and there seems to be some problem with delivering 
page faults (they look just fine in QVM86 traces, but in the OS and 
user-mode QEMU part I'm getting page faults at address 0x52 and 0)...

In any case the host system shouldn't crash and that's something I 
consider as a real problem. Would it be possible for you to mail me 
privately the contents of your C:\WINDOWS\Minidump folder (see 
http://support.microsoft.com/kb/315263/?sd=RMVP&fr=1 for details)?
