crash bug in MuseScore 2.0.2 revision f51dc11
I was running MuseScore Portable 2.0.2 on Windows Vista Home Premium Service Pack 2 (32 bit), on a very old laptop with an Intel T2060 with 2 GB of memory. I didn't have a lot running on the machine (a PDF viewer, Bing Desktop, and Windows Explorer. I didn't even have a browser running.
However, I was transcribing a large score (about 18 staves, 485 measures, 144 kB mscz so far), and I have been getting low memory warnings from Windows from time to time.
The error message was something along the lines of "The C runtime library has encountered an unexpected [maybe unhandled] error and must be shut down." I clicked on the dialog box "OK" button (neglecting to copy down the exact error message) and MuseScore went away.
My best guess is that some memory allocation is failing, and the exception handler chain doesn't know how to fail gracefully.
When I started again it offered to resume from the auto-save file, I said yes, and it said that the auto-save file was corrupted. (Fortunately, I save manually fairly often.)
This could be counted as two bug reports (the crash and the corrupt auto-save file), but this is only meant to report the crash. I will file a separate auto-save bug if I can find the auto-save file.
