Oh well.
My self-compiled minetest is crashing with a segmentation fault immediately after startup. It's the very first thing it does, no other messages are shown.
It was running just this morning and after a dist-upgrade (on Debian testing) the bug appeared.
I configured with
Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

cmake -DRUN_IN_PLACE=TRUE -DBUILD_SERVER=TRUE -DBUILD_CLIENT=TRUE -DCMAKE_BUILD_TYPE=RelWithDebInfo -DENABLE_LEVELDB=TRUE -DENABLE_REDIS=TRUE -DENABLE_LUAJIT=TRUE -DENABLE_SYSTEM_GMP=TRUE -DENABLE_GETTEXT=TRUE
Running with valgrind gives the following output:

So there seems to be a problem in libgnutls somewhere. I don't know.
Because this was mentioned in another thread: The output of `ldd ./bin/minetest`:
