Bug#1050302: libcoin80c v4.0.0+ds-5 makes Freecad crash

[mattux]

Package: libcoin80c
Version: 4.0.0+ds-5
Severity: important

Dear Maintainer,

This is my first bug report and I hope I'm filling it correctly.

I'm a french debian testing user (I sticked to bookworm till last week) and I'm
facing a problem using FreeCAD which seems related to the libcoin80c package.

When opening a file in FreeCAD, the software crashes with an error message :
freecad: ./src/glue/gl.cpp:2354: const cc_glglue* cc_glglue_instance(int):
Assertion `current_ctx && "Must have a current GL context when instantiating
cc_glglue!! (Note: if you are using an old Mesa GL version, set the environment
variable COIN_GL_NO_CURRENT_CONTEXT_CHECK to get around what may be a Mesa
bug.)"' failed.

I used the "COIN_GL_NO_CURRENT_CONTEXT_CHECK=1 freecad" command as advertised,
and the software didn't crash.
I reverted back to v4.0.0+ds-3 from stable and it didn't crash too.
So I'm keeping v4.0.0+ds-3 pinned to have a working software without having to
use the command line.

I'm not very regular in reading my emails but I will try answering to your
questions dilligently.
Thanks.
