save game before a crash

comment:1 by vvs-, 3 years ago

Unfortunately, this is not easily reproducible from the saved game. Though, I was able to crash it again after many attempts. Alas, I don't have ScummVM compiled with debug information. But anyway, here is backtrace:

It most likely depends on the location of the text bubble on the screen. Is this a release build? I'm asking because there should be an assert to catch a potential error in copyBlockPhys() already. This it looks like this isn't triggered.

It looks suspicious, that we are validating a different rect in Redraw::drawBubble than we sending over to the copyBlockPhys call.

Talking about:

if (_engine->_interface->textWindow.left <= _engine->_interface->textWindow.right && _engine->_interface-> <= _engine->_interface->textWindow.bottom) {

_engine->copyBlockPhys(renderRect, true);


should maybe be

if (renderRect.left <= renderRect.right && <= renderRect.bottom) {

_engine->copyBlockPhys(renderRect, true);

Is this a release build?

It's configured with --enable-release. I could try a debug build instead, but I doubt this would help in this particular case.

Ok, thanks. Let's hope it's fixed for good.
