The very same CI job also had an error in "test (nightly, short, ubuntu-latest)", but it looks different, so this may just be a coincidence.

[fingolfin]

Note that the crash above is on OSCAR master, but it can also be seen on e.g. on PR checks such as in this log

[benlorenz]

This looks like #3296 which we have seen infrequently for quite a while. Maybe it would help to finally switch to a more recent libcxxwrap since these backtraces usually include some CxxWrap initialization.

[fingolfin]

OK, so I am all for switching to a newer CxxWrap. But maybe let's wait till after the Begehung to tackle it?

What needs to be update

• libsingular_julia_jll
• Singular.jl
• libpolymake_julia_jll
• polymake_oscarnumber
• Polymake.jl

Anything else?

[benlorenz]

I think these should suffice.
I don't really know if this will fix anything but we should do this anyway, also to get Oscar running in the PkgEval tests again (because of some assertion error that the old CxxWrap is currently triggering).
