I have the following issue:

```julia
julia> using Mousetrap
[Info: Precompiling Mousetrap [5deeb4b9-6e04-4da7-8b7f-c77fb1eae65e]

[25147] signal (11.1): Segmentation fault

```

I already reported this as bug, [On Ubuntu 22.04 with Nvidia driver moustrap 0.2 crashes · Issue #25 · Clemapfel/Mousetrap.jl · GitHub](https://github.com/Clemapfel/Mousetrap.jl/issues/25)  
but perhaps here somebody has an idea how to debug this kind of issues?

I created a virtual machine with Ubuntu 22.04, and there it works fine…

It also works with the nouveau graphics driver, but not with the official nvidea graphics drivers, which is strange…

Does anybody know how to run Julia under GDB to get a proper stack trace?

Is it needed to create a debug build of Julia to debug the crash in this library?

Yes, a `make debug` is needed if you want good stacktraces.
