Sounds like you have some memory problems in your program, and they are
tromping on LightSpeed's heap.  I'd look for pointer problems.

It is a little known "bug" in LightSpeed that if you somehow write a program
than manages to corrupt the CODE resources stored in your project file, they
will stay corrupted until that segment is modified or you do a complete
rebuild (see above).

I really believe your problem is with your program.
