Ogre crash introduced with rendering fix

[werdanith]

I get this crash when I coc to Pelagiad, Vivec, Caldera or Seyda Neen and I don't see anybody else complaining.

Code: Select all

openmw: /build/buildd/ogre-1.7.3/OgreMain/include/OgreAxisAlignedBox.h:252: void Ogre::AxisAlignedBox::setExtents(const Ogre::Vector3&, const Ogre::Vector3&): Assertion `(min.x <= max.x && min.y <= max.y && min.z <= max.z) && "The minimum corner of the box must be less than or equal to maximum corner"' failed.

I checked with git and the merge of the branch renderingfix introduces it.
I'm using Ogre 1.7.3.
Is anybody else getting it?

[werdanith]

Upon further inspection, it's exactly this commit that causes it
c471aa950f89bf674a49d7ea2f5a385643954eb5
When I revert it from master the game works ok.

Edit: lgro reports that he doesn't get it with: community/ogre 1.8.0RC1-3

[Zini]

Well, I don't get it either. OGRE 1.7.1, though.

[werdanith]

I got the source of Ogre, compiled and installed version 1.7.1, completely recompiled OpenMW, and I get exactly the same error. What's next? Could it be a hardware issue?
I have a Radeon X1950 Pro with the gallium3d drivers, Mesa version 7.11
Could it be a different component causing it?

[Zini]

I don't see how this could be hardware or driver related, because the crash seems to be caused by something related to bounding box calculations.

Well, no idea. I would suspect that there are other subtle differences with your setup, but it seems you have mostly ruled out that already.

What you could try is to get a stack trace by running OpenMW in a debugger.

[werdanith]

Ok, time to figure out how to do that.

[Zini]

Hint: When running OpenMW under a debugger, don't forget to use the --debug switch (see ./openmw --help for details).

[ezzetabi]

Is openmw compiled with symbols by default?

If so it should be enough doing:
gdb
file /usr/bin/openmw
run
<crash>
bt

My copy has no symbols, how can I compile with -ggdb? Is there an easy way?

That tells us at least that you have identified the right commit. The crash happened while building the static geometry, which was disabled prior to this commit. Right now I have no idea what could be causing it.
