It is difficult to reproduce, blender crashes without windows notification and there's no crash.txt in the TEMP directory.
But on MacOSX I found crashlogs.
Code: Select all

Exception Codes: 0x0000000000000000, 0x0000000000000000

Termination Reason: Namespace SIGNAL, Code 0xb
Terminating Process: blender [599]
