[minetest-server] segmentation fault on aarch64 (tcmalloc?)

[popsUlfr]

Hi,

trying to install minetest-server aarch64 version and running minetestserver immediately ends with a segmentation fault in tcmalloc and finally in libunwind it seems.

I think leveldb pulls in tcmalloc, alpine simply does not use leveldb from what I can tell : https://git.alpinelinux.org/aports/tree ... t/APKBUILD

So I'm trying to recompile minetest-server with leveldb support disabled to see if that works around the problem.

But the tcmalloc issue might plague other packages too.

EDIT: I can confirm now that disabling leveldb in minetest-server makes it work.
