OpenMW 2023.04.10: crash on startup

[krogg]

This is on a Linux 64 bit (intel x86_64 aka amd64, not multi-lib) system.

The version of OpenMW was fetched from github on 2023 April 10th and compiled without incident.

When starting OpenMW, the following sequence of events happens. The launcher appears, presenting the list of mods. OK so far. I click Play. The video plays, with sound. OK. The game then begins the usual display of random load screen pictures. OK. The next step is for the game to display the new / load / save menu. It does not do this. It crashes. By crash, I mean close the window, put up a small dialog box explaining where the crash log is an a button to close it.

I've no idea what is going on. This is the first time I've had this error. Has anyone else had this error? If so, how did you fix it?

Attached is the OPenMW crash log (approximately 58 k)

Thank you.

p.s. This also happened with a (now removed) version of three or so weeks earlier: this version had been fetched & built in the hope that the problem had gone away.

You've somehow managed to call a null pointer as if it were a function. That's not normally something that could happen without lots of people reporting it, so the obvious first questions are what your settings are and what mods you're using.

[psi29a]

Since you compiled it yourself, can you list the versions of the libraries you linked to, for example OSG?

Also, dates are meaningless, do you have the precise commit?

Which OS?

[akortunov]

More likely it is a yet another issue related to the unstable crocus_dri driver.

[AnyOldName3]

All the past Crocus crashes have been within Crocus itself. This is crashing in OSG. It's more likely that there's a bug on our end or with OSG.

[krogg]

Thank you to everyone who replied. Much appreciated.

Would the log of the configure (err, I mean cmake) phase help? If so:

Since some of the dependencies (such as recastnavigation) are auto-fetched and discarded at compile time, I can't report every version.
in the hope that my actual cmake command provides clues, here it is:

Also, dates are meaningless, do you have the precise commit?

I don't understand this question. When I get a package from git and I want the current (not the one in the .zip file) version, I perform a

Code: Select all

git clone https://url.of.gitsite/projectname

and trust that someone else is not modifying one of files at the exact instant I'm fetching and hope for the best. I then tar it up as if it were a traditional tarball and work from that. Since version numbers are not apparent with the clone approach, I use the date I fetch it as the version year.month.date. I'm sorry I can't be more precise.

Normally the git revision is listed in the launcher. But you can see that by running `git rev-parse HEAD`

Interesting... have you tried one of our flatpak RCs or generic linux builds? Just to first validate if they crash too?

[AnyOldName3]

Normally the git revision is listed in the launcher.

This'll only work if the source code is still an intact Git repo when CMake runs. Depending on how the user's 'tar[ring] it up', the .git directory may cease to exist.

Just wanted to add that I recently experience the same crash behavior as OP, null pointer in OSG applyAttributeList.

I tried to do a bisect to narrow down the introduction point. Unfortunately I couldn't get anything exact due to the two moving variables (openmw along with OSG).

Builds failing with same null pointer (did more builds than this, but this just captures the outer edges of the bisect):

• - openmw: 5446906b309f9876f757c31be13a7d888ae95919, OSG: 69cfecebfb6dc703b42e8de39eed750a84a87489
• - openmw: e9cfc2381fb949e427901463225ac21cef279fbc, OSG: a827840baf0786d72e11ac16d5338a4ee25779db (first 3.6.5 merge after RC)
• - openmw: e4eeb9cce9b29702bfde7dc9fdd3b983a8d69249 (note same as good build below), OSG: 69cfecebfb6dc703b42e8de39eed750a84a87489

Build that doesn't crash at the same point:
- openmw: e4eeb9cce9b29702bfde7dc9fdd3b983a8d69249 (most recent version I could build against OSG 3.6.1), OSG: 4665a2f03368be95f4773463f733dbdd88f63c5f (last 3.6.1 version)

Summary: OSG 3.6.1 fine, OSG 3.6.5 crashes

As a sanity check I tried against OSG mainline 3.6.5 and got the same crash

Other environment details:
OS: GUIX system 1.4.0
GCC: 10.3.0 and 12.2 (didn't seem to make any difference) (also tried building OSG with Clang-15, same crash)


If it helps, I also have a reliable repro that I've tried on two different systems, one intel and one AMD (not that I expect that would make a difference in this case)

See the attached games-repro-npe.txt file. If you have or get access to a GUIX build daemon, you can repro it with

Code: Select all

guix build -f path/to/attached

To get to a GUIX build daemon, either install guix as a package manager if your distro supports it, or get a VM image from https://guix.gnu.org/en/download/

[AnyOldName3]

That's got to be memory corruption. osg::ClipControl::apply doesn't dereference any pointers that can be null. It can't be down to Crocus drivers as you're on RadeonSI. We can't really say any more than that with the information we've got. What might help would be if you ran OpenMW through a debugger until the problem happened again and looked at what the memory being accessed looked like, as different causes would likely cause different patterns.
