this is a sample error message:
*** glibc detected *** /usr/lib/vmware/bin/vmware-vmx: malloc(): memory corruption: 0x000000000131cfe0 ***
======= Backtrace: =========

It happens at random times (most likely when the Windows 7 x64 login screen appears or when you re-run the assessment in control panel performance information and tools) when the virtual machine is configured to accelerate 3D graphics. I did not see this issue with 260.19.36 and earlier versions.
