You can try running under "valgrind" and that might help find the issue
(especially if you compile your program with '-g' to include debugging
information)

valgrind --log-file=/tmp/valgrind.out ./003/cxpmntdoc.4ae


Mainly - I'm guessing its to do with set_count or referencing arrays
outside their normal bounds..

If you can reproduce it in a simple program I can try here - I can take a
look ?
