[r64] Crash when loading maps

RazTK · Post by **RazTK** » Wed Mar 19, 2008 12:46

gzdoom -iwad doom2 +map map01

MAP01 is just an example. It crashes in every other map I tested.

Same here, right after a fresh SVN update to r64. Starting a new game crashes GZDoom.

How's r65?

New revision, new try...

Nope, still the same.

The crash is in gl_vertex.cpp at line 219:

Code: Select all

AddToVertex(sec, vt_sectorlists[v-vertexes]);

The problem first appeared in r62.

The strange thing is that I can compile it and it works. Have you tried a complete rebuild?

What's the error the debugger reports?

r66 crashes for me too. Compiling a release version went OK with no warnings. I started the exe - no command line just double clicking the exe, picked doom2.wad and GZdoom started. I brought up the menu and went through the choices to start a game and it crashed instead of starting a game. I didn't see the level on screen but I did hear d_runnin. This is repeatable and seems to happen in exactly the same way with all IWADs.

I always do a rebuild. :>

Any helpful information here?

Hm, that's weird. There seems to be a discrepancy between my local code and the repository. It's the only explanation I have. I'll do a separate checkout and then compare the files. I hope I'll find it.

Post by **Graf Zahl** » Fri Mar 21, 2008 19:51

I really don't know what's happening. I just got the entire project from the SVN into a separate directory and compiled it. It runs just as well as my other version.

RazTK · Post by **RazTK** » Fri Mar 21, 2008 20:43

Okay, I completely removed my local copy and did a checkout of the entire trunk directory again and it's still the same. What the hell is going on?

Something happened between r61 and r62 that's causing it not to work properly.

Post by **Graf Zahl** » Fri Mar 21, 2008 21:08

Can you zip your entire project directory, including EXE and object files and put it on RapidShare? Maybe if I debug that something pops up.

RazTK · Post by **RazTK** » Fri Mar 21, 2008 21:43

Here (right click and 'Save As'), I've uploaded it to my Diino account, I'm sure you'll find it more convenient than RapidShare.

Post by **Graf Zahl** » Fri Mar 21, 2008 22:03

Thanks. BTW, I just updated to ZDoom r833 without the new sound code and it still works fine for me. This has to be the weirdest bug I ever encountered.
