Segmentation fault during __init__ #459
Description
Our corresponding downstream issue is oscar-system/Oscar.jl#3904.
On julia 1.11, we randomly see segmentation faults during the execution of CxxWrap's __init__ function like the following one:
[3419] signal 11 (1): Segmentation fault

I believe we haven't experienced anything similar on 1.12-nightly yet (please correct me if I am wrong @benlorenz).
At the beginning of the above-referenced issue, we were still using an outdated CxxWrap. However, regarding the more recent occurrences, we are running with CxxWrap v0.16.0 and libcxxwrap_julia_jll v0.13.2+0.
