Even sfan5 said a while ago:
It seems something is seriously broken here.So far I've had no luck getting that mode to run without segfaults under stress testing (on Linux).
Would it be possible to just drop LuaJIT support from Minetest? It always seems the source of so many worries. I don't even understand why we have to support LuaJIT in the first place.
So the simplest solution seems to just get rid of it.
Or at least tuck it away in a branch until it's ready for prime time.
Note I do not understand the inner workings of Minetest, also, I am the opposite of a LuaJIT expert ;-) , so I might be mistaken here.
