segmentation fault on mac

[katosad]

Hello,
I am experiencing a strange segmentation fault issue when iterating over directories and generating ply files. I am running this on an M3 mac, OS v14.7, using PyMeshLab v2023.12.post2 & python 3.10.

Pseudocode

main.py:

for dir in os.listdir(root_dir):
    try:
         ms = generate_ply_files(dir)
         # do some other stuff with ms
    except Exception:
         print("error")

generate_ply_files:

def generate_ply_files(dir):
    ms = pml.MeshSet()
    ms.load_new_mesh(f"{dir}/mesh1.ply")
    ms.load_new_mesh(f"{dir}/mesh2.ply")
    ms.apply_filter("generate_boolean_intersection")
    return ms

Behavior

My root_dir has the following structure:

root_dir
| - dir1
|    | - mesh1.ply
|    | - mesh2.ply
| - dir2
|    | - mesh1.ply
|    | - mesh2.ply

If i start with processing dir1 and an error is thrown from generate_ply_files, then I receive a segmentation fault when I move on to processing dir2. The seg fault is triggered when calling ms.load_new_mesh('root_dir/dir2/mesh1.ply'). If no errors are thrown when processing dir1, then no seg faults occur either.

I hope this is clear, but let me know if you need anything else. Thanks!

That's strange, and it seems very difficult to debug.
I don't even know where to start since a new MeshSet instance is created every time...
What kind of error is thrown when processing dir1? Have you tried the same example on other platforms?
