Errors in truck 4737

[Ironfist]

Having just updated to trunk 4737 I am now getting crashes I have not changed any OXPs from trunk 4702 which was the last trunk install. There are not error messages in the debug console or the log. I will download the source and do a make debug=yes.
System is XP32 SP3 with latest updates

Quick update have used SVN to provide latest source and did a make clean make debug=yes.
Got a similar crash to previous one from Trunk
Running under gbd I get this in the terminal screen

Code: Select all

Program received signal SIGTRAP, Trace/breakpoint trap.

What does "bt" in the gdb prompt return as output after a crash? Also, please check for the existence of stderr.txt following a crash and post its contents, if it's present and its size is bigger than 0.

[Ironfist]

Should have thought to do that

Looks like backtrace is next to useless in this case. What about stderr.txt? Any luck there?

[Ironfist]

No completely empty I am afraid.

Should have said this happens when using the cheat jump mode in 'Long Range Scanner' to jump across about 4 systems - not sure if that is important or not.

Ironfist

[another_commander]

Can you please describe in precise steps how to reproduce the crash, using the minimum number of OXPs installed?

[Ironfist]

Tried to reproduce the crash with just 'Long Range Scanner' loaded and a new Jameson - no luck.
I will therefore take some time to see whether it is related to the amount of OXPs I have loaded and report back maybe tomorrow.

Is your ship cloaked while doing these jumps?

[Ironfist]

No no cloak, from playing around all afternoon and some of this evening it looks as though it has something to do with the number and/or size of all the addons. But it is not consistent enough to come up with a definitive answer yet. I will keep going to try to get something repeatable.

What OpenGL level support does your graphic card show in Oolite's latest.log file?
Is there a newer graphics card driver (OEM in particular) available for it?

[Ironfist]

Log shows this

Code: Select all

21:07:58.218 [rendering.opengl.version]: OpenGL renderer version: 4.2.11318 ("4.2.11318 Compatibility Profile Context"). Vendor: "ATI Technologies Inc.". Renderer: "ATI Radeon HD 5700 Series".
21:07:58.218 [rendering.opengl.extensions]: OpenGL extensions (210):

this is the December 2011 driver for the card.

Currently it would appear to have much more to do with the amount of OXPs loaded rather than the actual OXPs or the number of them. 240Mb appears to trigger the problem, machine specification is:-

XP32 SP3 with all updates
Intel E8400 running at 3.6GHz with 2GB of ram
Graphics ATI Radeon HD5750 with 1024MB
