Arch Linux

same here. Since the update is only an rebuild against libpng16, I tried to roll back only wesnoth and installed libpng15 from aur, the problem went away.

Here is the backtrace from core dump. I didn't compile wesnoth with debugging symbols.

(gdb) bt

#10 0x000000000087bc4c in game_controller::init_config(bool) ()
#11 0x00000000006afba2 in _start ()

For me it works for some time but then crashes randomly with segfault.

I also have the same problem. After deleting the cache files, Wesnoth now hangs during load. Here is a debug build backtrace:

Looks like there is an upstream bug for it: https://gna.org/bugs/index.php?20742

The forum patch solves the the problem for me:

Since this patch is already upstream and was only forgotten in this release, it might be possible to patch in Arch until there is a fixed release of wesnoth?
