Another backtrace for the same bug.  (none of the others include
ProblemReporter's destructor)  Also, the procces is still running on my machine.
If a developer wants more information from gdb, please contact me in the nest
two or three days. Unfortunately gideon was not built with debuging symbols.

(Continuation of comment #5)It might be a multithreading problem; these are the
backtraces for the other two threads.

This seems to be fixed with the new cpp parsing code (in cvs). 

Moving all the bugs from the CPP Parser. It was not well defined the difference between it and C++ Language Support and people kept reporting in both places indistinctively
