Hi Daniel,
Thanks for sharing this issue.
Is there any UI action that seems to specifically trigger the crash? Or does it just appear at random?
A crash minidump would be useful if you have a way to share it, though considering their size I understand this may not be feasible. Are you able to get a stack trace of any kind?
NCrunch itself is 100% managed code and it's rather militant with its exception trapping, so if this is NCrunch's fault, it's likely to be quite indirect. It may be very hard to trace this problem.
