Segmentation fault

[chlin]

I encounter a problem that each time after the game has been started up and the map is shown on the screen, suddenly the game crashes (I may be able to drag and point the scout around to some place). The only message I get is `Segmentation fault'

The message printed on the console is

Segmentation fault

It looks like while in the loop of Frame() function (in main.cpp), at some points something goes wrong but I can not find it because I completely have no clue what happens. Also, I think this may not be the problem of the 0ad because at the moment my graphic card (ati x2300) is no longer supported by AMD (I use open source radeon driver instead which supports some basic 3d functions). However, I would like to check out what goes wrong considering this problem. Is there any clues on this? Or where (e.g. which .cpp file, etc.) I may go checking for finding more information?

In addition, I notice when doing test (./test_dbg), it throws a failure in testing

ERROR: JavaScript error: simulation/components/GuiInterface.js line 57
ReferenceError: IID_Identity is not defined

In TestComponentScripts::test_scripts:
../../../source/pch/test/../../../source/simulation2/components/tests/test_scripts.h:45: Error: Test failed: L"Running script simulation/components/tests/test_GuiInterface.js"
../../../source/pch/test/../../../source/simulation2/components/tests/test_scripts.h:45: Error: Assertion failed: scriptInterface.LoadScript(name, wcontent)

I appreciate any suggestion.

(Fixed the test error now.)

Can you run the game in a debugger to see where it's failing? (Run "gdb ./pyrogenesis_dbg" then "r" then wait until it fails, then switch back to the gdb window and do "bt full".)

Hi Philip

Thanks. Below is the output after executing gdb with pyrogenesis_dbg.

gdb shows that it terminates at

Program received signal SIGSEGV, Segmentation fault.
0xafaa333d in radeonEmitVec4 () from /usr/lib/dri/r300_dri.so

and `bt full' shows

That's crashing somewhere inside the driver code so it looks like it probably is a driver problem. (The code in FixedFunctionModelRenderer.cpp works fine on other systems so it seems less likely to be an error in our engine code). I'm afraid I have no idea how to go about debugging that kind of problem

Hi Philip

Thanks for your advice. The result is within my expectation; it is just a bit annoying that the support is unfriendly from the vendor. I will find an alternative way to get around it.

I appreciate your help.
