I was just driving in a city over some slimes and zombies, and suddenly the game crashed.

Its a [known issue](https://github.com/CleverRaven/Cataclysm-DDA/issues/2209)

Yes, it is. Looks like “Pull Request #2222: Fix to random segfaults” did not fix it.  
Should I delete this topic?

That PR only fixed one case of segfaults, though i could have worded it better…

And no need to delete this, as the crash log may help tracking this bug down.

You know, I looked into sources, and…  
One does not simply remove an entity from a list while iterating over the same list.  
You can’t just do remove\_field(x, y, fd\_…) in the “for(std::map\<field\_id, field\_entry\*\>::iterator field\_list\_it…”-loop.  
It is folly.

Good find, made a [PR](https://github.com/CleverRaven/Cataclysm-DDA/pull/2574) for it.

Thanx. But this bug is still present in process\_fields\_in\_submap’s “for(std::map\<field\_id, field\_entry \*\>::iterator it…”-loop.

Seriously. Without something like this

` if (!skipIterIncr)
                            it++;
                        skipIterIncr = true;`  
in “Totally dissapated” case the game crashes on it++ after grid[gridn]-\>fld[locx][locy].removeField(cur-\>getFieldType()).

Have you pulled the latest experimental? IIRC this has been fixed already (thanks to the results of this thread).

The only part of the version number that will update is the big long string (XqQd483jsdscfegz-type stuff) at the end. Everything else remains the same until we manually tell it to update prior to the next release.
