Segmentation fault on macOS (Frama-C GUI)

[maroneze]

Hello,

When trying to run the Frama-C GUI on macOS, I'm getting a segmentation fault, and I'm not sure where to start debugging.

The issue seemed similar to what happened in CoqIDE, but even with lablgtk.3.1.2, it's still happening.

In case there is something that would seem obvious to you, I'm pasting the trace of running lldb on the compiled frama-c-gui binary. This is from the development version of Frama-C; unfortunately it is currently hard to install the latest stable version in macOS due to an issue (we created a patch but the PR has not yet been merged in opam-repository).

The opam switch has been exported to the file below. It uses OCaml 4.13.1, lablgtk3.3.1.2, lablgtk3-sourceview3.3.1.2. I'm not sure which other packages would be relevant.

I'll try to provide a more reproducible environment and see if I can better understand it.
