That solved it, thank you very much @Fyre

Furthermore, the mentioned code seems fine:

https://github.com/mangoszero/server/blob/master/src/game/vmap/TileAssembler.cpp#L390

I'll continue working on this. I'll update the thread when I find a solution. Since the code is fine, there's not much the project can do about this, it seems to be a gcc bug, not mangos. I'll start by comparing the build logs on github with the package versions I'm using.

Thank you. I've verified the memory is not saturated and repeated it twice. At the point of crashing, this is how much memory my system had free:

               total        used        free      shared  buff/cache   available
Mem:           3.8Gi       588Mi       2.1Gi       5.0Mi       1.1Gi       3.0Gi
Swap:          8.0Gi          0B       8.0Gi

Additionally, I watched it and logged the memory output with "while true ; do free -h >> memory.txt; sleep 2; done". Everything seemed ok.

I will attach the compiler output to this post. Inside it are two errors:

I'm building mangos zero on Ubuntu 22.04 LTS, I'm encountering an "internal compiler error", in response to what I believe is valid code, how can I avoid this?
