[resolved] Heap Corruption (0xc0000374) crash on vid_restart

[draeath]

Hey folks,

 

I just started playing "No Honour Among Thieves" after doing the "A New Job" and "Tears of St. Lucia" and have found a crash bug of some sort. While I've since fiddled with my cvars, the issue first occurred with the settings I'd used without issue on the prior missions. I'm using the 2.10 release.

 

Initially starting the game and starting the mission (or loading a save) works fine, but should video have to be reloaded (ie after death, or issuing a "vid_restart") I get a crash to desktop, every time.

 

I was able to debug this down to heap corruption, but without PDBs I can go no further (I can't find or have no access to the "assets SVN" where these would be, based on the wiki). Please find attached various potentially relevant config files. I have a crash dump, and will try to edit a URL in to it after initially posting it (worried about anti-spam measures). Just in case, I've included windbg.txt output in the attachments showing what I can as-is.

 

I've already ruled out  r_useMultiDrawIndirect and r_useBindlessTextures (and so you'll see them on in the attached files, since they didn't seem to be at fault.

(I have modified alsoft.ini, to force headphone stereo mode.)

adding version number

OK, crash dump is uploaded and is available here (removed in edit, since the issue is known) . It's not small (compressed down to 554M) so please only grab it if you need it, to spare me the bandwidth.

 

I'll be resetting my settings and being less adventurous with things that aren't menu-accessible, meanwhile.

 

EDIT: ok, yep. the issue is no longer present after resetting my cvars. Here's a unified diff (- is the crashing config, + is the noncrashing config). Some differences are totally unrelated I'm sure, just me not being consistent when going through the menu options.

removed dump link

OK! Nailed it down, I think. It seems that the culprit is setting r_useBindlessTextures to 1, for this mission (nhat3/politics) at least.

[nbohr1more]

Yep, bindless textures is flakey on many drivers. The negatives outweigh the positives on that feature so it has been removed from the next release.

[draeath]

Ah, thanks! I appreciate the confirmation.

Which makes me a bit sad, when AMD finally fixed their OpenGL drivers, I was getting a good performance boost from that feature.
