Oolite crashes randomly.

[JakeJ]

I've got a problem (I hope this is the right place to post it). Oolite 1.82 keeps randomly crashing on me. I guess it could be that I'm running it on a fairly old laptop, but 1.77 works fine. I'm running Ubuntu 14.04. I haven't noticed any particular event that causes it to crash, it just seems happen whenever it wants, sometimes right after I start the game, and sometimes a good while into the game. I tried running it in the terminal, and when it first starts I get this:

It seems that your operating system does not have a valid timezone name
configured and is using an abbreviation instead.  By comparing timezone
file data it is has been possible to find the actual timezone used, but
doing that is a slow process.

You can avoid slowness of this time zone detecting approach
by setting the environment variable TZ='US/Pacific'
Or You can override the timezone name by setting the 'Local Time Zone'
NSUserDefault via the 'defaults' command line utility, a Preferences
application, or some other utility.
eg "defaults write NSGlobalDomain 'Local Time Zone' 'US/Pacific'"

AL lib: (WW) alc_initconfig: Failed to initialize backend "pulse"

But it starts up and runs for a while anyway, then when it eventually crashes, I get this:

Code: Select all

*** Error in `./oolite.app/oolite': double free or corruption (!prev): 0x0af99ed0 ***
Aborted (core dumped)

Erk. It looks like Oolite died with an error. When making an error
report, please copy + paste the log above into the report.

I'm not sure if it's a problem with the installation, a bug, or just my peice of junk computer. If there's someone who knows a bit more about this than I do, I would sure appreciate a little help.

Welcome to the forums.

Could you start up Oolite, then quit from the menu screen, and then post the contents of your Latest.log file here, please.

Here it is.

Unfortunately the Intel 945 is probably the problem. It's not a great card for OpenGL support, and we've had people have trouble using it with Oolite before.

If you haven't already done so, reducing the graphics setting level to "Normal Detail" or "Minimum Detail" might make things more stable.

(You might also have some luck upgrading Mesa, but that usually has enough other knock-on effects that you might not want to try it)

[JakeJ]

I'm already running it at minimum detail, and I don't really want to mess with trying to upgrade Mesa right now. Oh well, I guess I'll just have to try it with a different computer. Thanks for the help anyway.
