CB nightly build svn 12748 froze while typing in the editor. It was a deadly crash which also slowed down the whole system (win7) causing an hard disk error. Rpt included. Note that I have CB installed in D, despite that after the crash I had to repair my syatem SSD!
The RPT shows the last C::B fuction was "ConfigManager::GetUserDataFolder", which does not write to the file system. I think the problem you have seen with C::B was a symptom of something else like the SSD or MB (motherboard) or RAM or Windows or some another app else failing that then caused Windows and/or SSD to become corrupted. The Windows/SSD corruption then caused C::B to fail. I would check the SSD smart statistics to see if you can find what the problem is.
The last C::B function in the RPT file is:
I would be very careful with the SSD and the MB as the corruption may indicate that the SSD and/or MB are starting to fail. I have seen this with HDD in the past where an app crashes and the HDD is corrupted with I restart the OS and when I checked the low level HDD it's SMART stats indicated it was on the way out. I replaced the HDD and then the problems started occurring where it took me multiple times to get the data off the dying HDD.
