Upgrading Erlang to 20.1 makes Wings crash when creating a cube

[xyproto]

Hi,

For Erlang 20.0.1, the following steps work fine, while for Erlang 20.1, it crashes Wings:

1. Start wings3d.
2. Create a cube (right click and then select "Cube").

This is for Wings 2.1.5.

I'm on 64-bit Arch Linux, where I maintain both erlang and the wings3d package.

Here is the output on the terminal:

wings-2.1.5
Reading preferences from: /home/afr/.wings3d/preferences.txt
Using GPU shaders.
/usr/bin/wings3d: line 4: 13978 Segmentation fault (core dumped) erl -noinput -smp -pa /usr/lib/erlang/lib/esdl-*/ebin /usr/lib/wings3d/ebin -run wings_start start_halt ${1+"$@"}

I see no core dump file.

Removing ~/.wings3d makes no difference.

Other users have been able to reproduce the problem.

Could this be an issue with Erlang 20.1?

Best regards,
