I'll try your ideas on how to track this down. I wonder if I am really having some kind of other issue... maybe RPOS is using the stack and I'm running out of space or some other kind of memory issue. It seems odd that I can run this routine dozens of times successfully and then I get this access violation... with the exact same input it was fine with one loop earlier. I also have access violations in other procedures. I have a sequence that produces it here... but other sequences produce it in other places. Is there a way I can output various memory areas to see if it's really a memory related issue? Something like a writeln for stack space etc?

To do anything we will need a compilable short fragment of code demonstrating the bug. Sometimes this can be done by just taking the existing source and start removing code that doesn't seem to influence the code, and passing constants instead of whereever you get your filenames. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
