9093	Fatal Error in Recompiler CPU (MINIX 3.1.9 exp.)	pikpik		"Hi,

I was installing packages inside the guest and operation was normal, until I saw strange messages filling the guest's screen and then a message from VirtualBox appeared.


'''Basic transcript'''

Install image

Shutdown

Remove image

Start

{{{
# pkgin update

# pkgin install scmgit-base-1.7.3.4nb3
}}}

Normal operation: packages download and several install

Later, this line repeats many times:

{{{
WARNING wrong user pointer 0x7ffff9bc from process sh*F / 146430
}}}


After several moments, the following message appeared from VirtualBox:

{{{
A critical error has occurred while running the virtual machine and the machine execution has been stopped. [...]
}}}

I found this short log file (2011-06-21-11-33-21.051-VirtualBoxVM-527.log) in the Applications folder on the host system:

{{{

'''Other information'''

Guest: MINIX 3.1.9 (experimental image)
Image: http://www.minix3.org/download/minix3_1_9_ide_r9618.iso.bz2

This hasn't happened before for me for several versions of MINIX and VirtualBox. Because this is very rare (it occurred only once in about a year of frequent use), I'm listing this with a minor priority.

Thank you,
