General description:

Running a GUI application that reads files, processes then and writes new files. As files are processed GUI displays the file name and a progress bar. 


 Application should finished running without crashing.

What happens: 

Application crashes intermittently (about 1 in 10 times) with a stack trace from C code. Can only reproduce so far a second Mono GUI application running on the same Desktop. In this case MonoDevelop.

See attached crash1.log file for stack trace and how Application was started. Replaced name of executable with <EXE>.

System info:

 CentOS 6.5 64bit
 $ mono --version 
Mono JIT compiler version 3.10.0 (tarball Sat Oct  4 15:25:02 UTC 2014)

        GC:            sgen

Additional info:

 * Application was started with --debug flag to see it would print extra info. But it was crashing without the --debug just as much.

 * MonoDevelop 5.7 was up and running in the background in a different windows on the same Desktop. If MonoDevelop is not up could not reproduce the crash. Mentioning it just because this might be significant.

This is a windows.forms application, and mono no longer supports windows.forms.
