This?

We shall see. Though, didn't you list another critical bug in conjunction with this one some time back? I think you did, but I can't at all remember what it was.

I hope that happens after fixing this.

So...

Since this was the biggest obstacle for a 2.6.0 release, will it come now?

Fixed.

So, the problem also happens with Virus MAP03.

I can't reproduce the freeze in r3179, I'm using linux, release and debug builds.

As per GZ's request, here's my map that reports an error in the console when the polyobj is activated:
cr_26.7z
This is the message that pops up in the console:

Code: Select all

SelectVertexClose selected endpoint of seg 11
Last tested with R3152. It doesn't crash, freeze or anything though. As far as I can tell, everything works just fine.
[EDIT]
Still happens in R3279, and again, it doesn't crash or freeze me. I just get the message in the console.

This issue is nothing new.

Here you find more info about the problem. It can be avoided but it wasn't done yet because it would have an impact on performance and no map ran into it since the last round of fudging.

But I leave this to Randy. He knows this stuff better and may find another solution.

Alright, so the dynamic node building algorithm introduced for the enhanced polyobjects is hitting an infinite loop? I guess the question from me then is this is a bug or problem with the algorithm or is there something incorrectly set up with my polyobject?

Re: [r3008] ZPack freeze

It runs into this error condition while building the BSP for the rotating polyobject:

Code: Select all

Printf("SelectVertexClose selected endpoint of seg %u\n", set);
(nodebuild.cpp line 831)

and if that happens the node builder goes into an infinite loop.

I wonder if it is related to the crashing I got when verifying the bug from this thread?

I reported it here.

http://forum.drdteam.org/viewtopic.php?f=24&t=5315

It's probably not it though because I only started noticing it with the latest GZdoom.

Well, I will try to reproduce it again as soon as I can. It's pretty easy to do, I know the places where it will crash. :)

Wrong reaction! You are supposed to post a bug report with the crash log. Now it can't be investigated anymore.
