Version: 1.7.3-5
Severity: important

Dear Maintainer,

Attempting to run Rig of Rods using debian provided libogre package.

Fault exists in 1.7.3-4 on for sure.  1.7.3-3 was unable to be tested due to
not working.  Have not tested before 1.7.3-3.

Disabling Plugin_PCZSceneManager.so and Plugin_OctreeZone.so allows programs to
work.

Valgrind fault  report is attached.  Appears to be libogre internally
triggered.

Hello,

Thanks for your report and your interest in improving Debian.

The function in question is just this:
PCZone* PCZSceneNode::getHomeZone(void)
{
        return mHomeZone;
}

This cannot crash by itself, the problem is that "Access not within
mapped region at address 0x218", which means that probably the region
holding the pointer is corrupted with the value 0x218.  mHomeZone is
always initialised to 0 in the constructor.

Even if this is caused by OGRE (rather than other code using the
libraries), the actual problem is elsewhere.  Please, try to spot the
reports from valgrind where it talks about memory being overwritten or
something like that.  (Taking a look at
http://valgrind.org/docs/manual/mc-manual.html might be useful).

Also, a new upstream version 1.7.4 has been uploaded since this bug
was reported.  Please try to confirm whether you can reproduce the bug
with the new version.

Regards.


PS: marking the bug as "moreinfo", please provide more info within a
few months, otherwise the bug will be closed (insufficient information
to track it down).

So closing now, due to lack of feedback or new reports (neither in
Debian nor Ubuntu) after several months and new releases.
