Yes, I noticed it only occurs when running ScummVM under valgrind though. So maybe timing related...

Very strange, then... Kirben, I assume *you* can still reproduce it? If so, anything more specific regarding how you reproduce it?
comment:14 by , 20 years ago
I'm unable to check right now, as I don't have access to linux at the moment.

The problem still occuring when running ScummVM under Valgrind, I even tried with boot patam 550, in case the saved game was bad.
Attached fresh saved game, where I can always reproduce issue: Run ScummVM under Valgrind, with that saved game. Exit left side of screen to main road. Enter mine road at first turning point. Esc anytime during the 'entering mine road' smush and error will occur.

Just FYI, I can't reproduce any problem there on Mac OS X, using the provided save game.
Maybe you can attach the Valgrind log?

I can still reproduce the error sometimes with latest ScummVM cvs.
I attached a valgrind log, but it doesn't report anything useful before the error occurs.

This sounds a lot like a race condition, though looking over the code I see nothing obvious.
Or maybe Eugene's guess is right that somewhere memory is overwritten (Valgrind can only detect if we overwrite memory which is not allocated -- it has no way to know whether we overwrite allocated memory "correctly" or not).
See also bug #933631 and #1087234.

I just fixed a SMUSH/INSANE race condition (I think), no idea if that will affect this bug, but if anybody wants to do a retest... :-)

I fixed the valgrind warning but unfortunately it still errors at that point every time. I have attached a save game, go back onto Main Road, turn into Mine Road at first sign and esc when entering Mine Road sequence is shown.
