Compiling sysutils with -gl gave the call stack seen below... insightful, I suppose, but not necessarily useful ;)
It definitely points to what Peter said about the ansistring finalize writing to the same place in the stack. Examining the stack, it seems that dump_stack calls get_caller_addr, and then I assume the access violation is about the address being unfindable since it's been overwritten. 1.9.5 (today's w32 binary) didn't work any better re: Peter's last comment: so I guess the finalization of that temp ansistring is done at the end of play_with_strings, rather than being done within play_with_strings just after completion of the call to do_nothing_with_an_ansistring ... but it still irks me that the temp ansistring is created even if the function requiring it is not called. Oh well. Has this been filed as a bug? (Is it considered a bug? I should hope so) ... for now, I guess I'm condemned to always be recompiling with a directive to either handle exceptions or see a call stack. I can live with that (as if I have a choice!) Thanks, guys... keep up the good work, I'm sure this problem will be solved eventually :-) ~David.
