[fixed]PAR1-4.WAD crash (No, NOT the missing linedef)

[nwbeeman]

Yes, I know e1m4 has a missing front sidedef. However, try this. Run GZDOOM with /levels/doom/Ports/p-r/par1-4.zip. Then type the following into the console map e1m4. Returns an error. Now, type it again, returns an error, eventually, if you keep trying to warp to e1m4 using map, GZDoom will crash with a VFE. ZDoom dosn't (Latest version of that one).

EDIT: Latest version of GZDoom

I just tried it again, type MAP e1m4 in console. Then press up enter and repeat as fast as you can. GZDoom will eventually crash. Error report below. Also, I attached the error report as well

Yes yes, I know its a case of dont do that, but I think Graf once said that nothing should cause GZDoom to crash like that. Besides, for all i know it could point to some bad code or a memory leak. Worth looking into.

[wildweasel]

Might be the memory leak that was reported a while ago - as far as I can tell, this'll happen with any map if you load it enough times in succession. With PAR, though, it goes much faster because it has more data to load.

Its sad that for some reason ZDoom fails at a line with no front side def, the first three levels are real detailed and fun to run around in

[Graf Zahl]

Then get the full 9 level version instead of the demo. Why only play half of it if you can have it all?

As for failing, a missing front linedef is almost guaranteed to crash the engine if not blocked.

Yes, but my point is the engine performs like its supposed to. It fails. But if you keep trying map e1m4, GZDoom then will continue to fail gracefully, then after awhile of executing the command map e1m4 repeatedly it then crashes to desktop with the VFE Any idea why?

[Graf Zahl]

Like WildWeasel I suspect that aborting the level load results in memory leaks that eventually become problematic.

Cool. Just thought i found a bug. I dont think it happens in ZDoom though. Oh well. Just another logdump to help try and find the cause i guess. tks

[MasterOFDeath]

Sorry for the offtopic-ness (If its offtopic) but there is a missing front sidedef in E1M4? Where?

Sorry for the offtopic-ness (If its offtopic) but there is a missing front sidedef in E1M4? Where?

Code: Select all

]map e1m4
e1m4 - Railbender    

Map has 218 unused sidedefs
Line 2970 has no front sector
Linedef 2970 does not have a front side.
The following lines do not have a front sidedef:
 2970

You need to fix these lines to play this map.

The full version of par does not have this issue

Of course not. The original was checked with MBF only, the final one also with ZDoom.
