hello world causes hard crash on Ubuntu 22.04

Hi, the following MWE project crashes on my and one of my users Ubuntu 22.04 machines:

OS Info
clem@ubuntu:~/Workspace/mousetrap_julia_binding/build$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy
I have been unable to reproduce this on fedora or newer ubuntu versions. I played with the cxxwrap_cpp definition and it seems only add_type causes the crash, other functions like set_const work fine. It happens for both mirror and non-mirrored types.
Just to make sure I did a fresh install on the current master of libcxxwrap and the issue persisted. Installation output:

Thank you
I am very much interested in getting this fixed. @barche Any idea how to debug this issue further?
@Clemapfel I am not able to reproduce the issue. I fail to compile the cpp program. I am having the output:
ufechner@ufryzen:~/repos/CxxWrap/build$ cmake ..
CMake Error at CMakeLists.txt:5 (find_package):
By not providing "FindJlCxx.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "JlCxx", but
CMake did not find one.
Could not find a package configuration file provided by "JlCxx" with any of
the following names:
JlCxxConfig.cmake
jlcxx-config.cmake
Add the installation prefix of "JlCxx" to CMAKE_PREFIX_PATH or set
"JlCxx_DIR" to a directory containing one of the above files. If "JlCxx"
provides a separate development package or SDK, be sure it has been
installed.
-- Configuring incomplete, errors occurred!
See also "/home/ufechner/repos/CxxWrap/build/CMakeFiles/CMakeOutput.log".
Any idea?
Ok, I could compile the code by using the following build script:
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=/home/ufechner/.julia/artifacts/88a033de19250acca6784647964d43d7121a06aa ..
cmake --build . --config Release
I obtained the prefix path from the command:
ufechner@ufryzen:~/repos/CxxWrap$ julia --project

Running the julia script works fine:

In other words, I cannot reproduce the issue.
@Clemapfel Can you please share the output of:
cmake --version
gcc --version
and the output of
using Pkg
Pkg.status()
We need to find out why it fails for you and works for me...
This might be related: https://github.com/JuliaInterop/libcxxwrap-julia/pull/132
I recommend trying this again with the just-released libcxxwrap-julia 0.11 and CxxWrap 0.14.
Reinstalling CxxWrap.jl and libcxxwrap.so from their respective github main branch fixed the issue for me.
I'll keep this open until CxxWrap.jl and libcxxwrap_julia_jll are upgraded and I can confirm this works for the installed-from-registry versions, but the just-released update does seem to work! Thank you.
Unless I am missing something, I have both (from the manifest):
[[deps.libcxxwrap_julia_jll]]
deps = ["Artifacts", "JLLWrappers", "Libdl"]
git-tree-sha1 = "15292484f628f2daaf77f7919f5df3d1719c86ca"
uuid = "3eaa8342-bff7-56a5-9981-c04077f7cee7"
version = "0.11.0+0"
and
[[deps.CxxWrap]]
deps = ["Libdl", "MacroTools", "libcxxwrap_julia_jll"]
git-tree-sha1 = "67ebbc028b385658142d3c0644e07992616653d9"
uuid = "1f15a43c-97ca-5a2a-ae31-89f07a497df4"
version = "0.14.0"
and am seeing this issue.
Note that you can't mix binaries from the Julia artifacts registry with code you compile yourself, maybe that is the issue? On Arch Linux I even have to compile Julia itself, along with libcxxwrap-julia and then the wrappers to make sure everything links correctly.
