do you mean that it cannot be a "unhandled exception" with ''crash'' and 
heaptrace dumping the thousands of left-behind memory blocks that weren't 
deallocated?? that's what i'm trying to get past... i want to see the error and 
unhandled exceptions but i really want to properly deallocate the 40000+ * 5 
records on the heap instead of having to either wait for heaptrace to finish 
dumping them or forcibly closing the task or (in the worst cases) rebooting the 
entire machine...

this is a console app based on tapplication (mainly for parameter parsing 
capability) and i have no clue (yet) how to catch exceptions and deal with them 

additionally, this last time i had to deal with this, fpc 2.6.4 release for OS/2 
was dieing with "unknown error 110" (IIRC) during runtime... i finally 
determined this to be from trying to reset a file that didn't exist where the 
path was pointing to... goofy error on my part that i fixed by fsplitting the 
pattern and adding the directory portion back to the initial directory path 
being used... in any case, i thought i should also mention this so that it can 
be corrected so it is not ""unknown"" any more ;)
