I'm not able to reproduce the crash with %WINDIR%\notepad.exe. Maybe this is reproducible only with a specific exe file?

It doesn't crash for me, but tries to open the file for a very long time with a constant 50% CPU usage. I killed the process after ~1.5 hours with ~400MB RAM usage.

Given that any unknown file type is forced to open in Writer with the ascii filter [1], I can guess why this happens. Not only it's a big file (117MB), the filter will treat special symbols like carriage return or form feed. Even notepad.exe (176KB on my system), opens with 666 pages. Now imagine what could be the results of opening your file.
