ugsvmt | Hello,
Ther's a tiling window manager (based on Penrose library) written in Rust which I'm trying to make it run on Alpine Linux. However, after compiling when trying to run the binary I get a "Segmentation fault" error.

Did you test the app on a different OS, or is this Alpine specific? Segmentation fault after the program compiled fine is suspect. | 40 | LearnRust |
