glDrawElements crash in CPatchRData::RenderBases

[Erik Johansson]

Much to our regret we must report the program has encountered an error.

Please let us know at http://trac.wildfiregames.com/ and attach the crashlog.txt and crashlog.dmp files.

Details: unhandled exception (Access violation reading 0x2EC010A4)

Location: unknown:0 (?)

Call stack:

(error while dumping stack: No stack frames found)
errno = 0 (No error reported here)
OS error = 0 (no error code was set)

After playing just say a minute or so at most the above did appear in an error dialog. Using the latest autobuild (from 10409) and SVN version 10427, but according to Ben it's an error in the terrain rendering code so that shouldn't be the problem.

I've had this problem on a Windows XP laptop with Intel graphics, usually when moving the camera around. I suppose if it's a driver issue, there is an error condition we should be checking to prevent a crash (since it's an memory access violation).

[Jan Wassenberg]

Given right to left param pushing order, it looks like the rightmost one to glDrawElements (indices=0x2ec010b4) is bogus. Although this value depends on registers still being valid, I assume so because it is close to the value reported in the exception.

Got another report of this.
