6649,Windows crash dump won't work properly with additions installed => Fixed in SVN,bifferos,,"Guest: Windows XP, SP2.
Host: Slackware 13.0 (also reproduced on Windows 7 host)
Reproduced with these versions: v3.1.4, v3.1.6

Steps to reproduce:
My computer -> Properties -> Advanced -> Startup and recovery.  Ensure memory dump is on.

Set the following registry entry (assumes PS/2 keyboard):
{{{
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters]
""CrashOnCtrlScroll""=dword:00000001
}}}


(Don't forget to reboot) This will allow you to 'blue screen' on demand.

Hold down right ctrl and press 'scroll lock' twice, to get crash dump.

Without additions installed, Windows writes a memory dump as expected.

With additions installed, the guest locks up, consumes 100% cpu and no memory dump appears.  Sometimes (but not always) the machine recovers and reboots, but in either case no dump is written.
