BSOD when a VM is shut down

[Rafcio]

This issue is not new, but finally I'm fed up. I thought that you get crash reports from Microsoft, but perhaps this is not the case. It's been perhaps a year that this been happening and no solution still. At least 4 out of 5 times when a particular Windows 7 VM is shut down (not when it's restarted only), it causes the BSOD (memory corruption) on the Windows 10 host. It's more likely to happen when the VM has been running at least several hours, but this is not a requirement. The below info is from the debugger, but I don't know how to debug that, only providing this as a proof it's VirtualBox (VBoxDrv.sys) that causes the crash.

BugCheck 1A, {1236, ffff8a871b92b000, ffff8a871b92b308, 242513}

• ERROR: Symbol file could not be found. Defaulted to export symbols for VBoxDrv.sys -
• ERROR: Symbol file could not be found. Defaulted to export symbols for VMMR0.r0 -

Probably caused by : memory_corruption

I can provide more info (just ask), perhaps even upload the memory dump for analysis, but I don't have the skills to analyze the crash dump myself.
