Upgrading Erlang to 20.1 makes Wings crash when creating a cube - xyproto - 11-02-2017
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,
Alexander F Rødseth

Dan warned me about to use the latest Erlang compiler due a issue related to WxWidgets - not sure it's causing what you are reporting.
Anyway, the current Wings3D version was built using the previous Erlang version - Erlang/OTP 20 - maybe the 19.3, but the 20.0 I have it installed and working - at least on Windows. (download all OSs and versions)

Same problem on Debian unstable. Had to do the following downgrade to get wings going again.
Will install 9 packages, and remove 1 packages.

Yes known bug and will be fixed in the next erlang release, sorry about that.
