#1709 DIG: Scummvm freezes

[Andreas Zautner]

The Dig (PC,english), Suse Linux 9.1 Kernel 2.6.5.-7.104
Scummvm 0.6.1b

After opening the third door (with the combination of
the orange engraved rod from the underwater cave) I
come by „tram“ to a steep coast scenario. When I try to
leave this scenario („up“) Scummvm freezes or crashes
down!!!

Regards
Andreas

I can reproduce this with 0.6.1b but not with the CVS
version. This is the relevant part of the backtrace I get:

So something about Digital iMUSE... strange, because that
part of the code is, as far as I can see, pretty similar
between 0.6.1b and the CVS version.

I've attached a patch that seems to fix it, but I'm not
entirely sure. The crash isn't 100% reproducable for me, so
it's hard to say for certain if it's gone.

The patch does fix the Valgrind warnings I got when running
it under Linux though.

Patch against ScummVM 0.6.1b

Well, if the patch fixes valgrind warnings, why not just apply it right now
anyway? No need to hold it back, is there?

Ok, I've applied the patch to branch-0-6-0, and added a
section to the NEWS file for a possible 0.6.2 (or whatever
it'd be) release.

Aquadran, do you think these changes are enough to fix the
reported bug?

i'm currently is off from scummvm, anyway it's possible
enough. There is hack for stopping sounds in imuse depend
for that param. it should be always disabled in the dig.

Andreas Zautner, can you still reproduce the problem with a current daily
build (available from our web page; or just build from the CVS sources
directly, if you know how to do that) ?

Thanks!

Hi fingolfin

With the current daily build of Scummvm I am getting quiet
good through the next picture (after the bug), but in the
next location after adjusting the lens there is the next
bug- the mouse coursor disappears.
(It still works while aktivating the menu.)

Thanks
Andreas

Thanks zautni. That would be another bug, though, please file a seperate
report for it. Thanks!
