In my experience, there's a lot of software between MPLAB and the running of
any given compiler.  The crash looks like an exception from deep within the
language runtime, which generally means that while there is a bug somewhere,
that kind of information isn't going to help us fix anything.

What I've found, though, on many occasions is, the problem is extremely
sensitive to the current working environment and any change at all will make
the problem go away.  So try the following.

-Try it again.
-Change something in the source code and try again.
-Close MPLAB, then run it again and try again.
-Reboot and try again.
-Create a new project with a different name, include the source code, and
try again.

Usually I reverse the last two steps, because it usually is something in the
project file, plus my project files are pretty simple, and I can make a new
one faster than I can reboot.

==Take Two==

There is one other thought I had. I used to be able to crash the CCS
compiler by invoking certain library  functions where I hadn't included the
appropriate .h file.  So, sometimes it actually is the source code's fault.
In that case it's good to ask "What did I just change?" and go back to a
previous version, if that option is available.  And one more thought...try
building some other project, just to test the sanity of the MPLAB+compiler
setup.
