EXC_BAD_ACCESS the first time after running a freshly compiled binary

[s-panferov]

System details

• OS/Platform name and version: Mac OS, M2, Sonoma 14.4.1
• Rust version (if building from source): rustc --version: rustc 1.80.0-nightly (d84b90375 2024-05-19)
• Notify version (or commit hash if building from git): 6.1.1

What you did (as detailed as you can)

1. Create a recommended watcher and default configuration
2. Add a file to watch

What you expected

Notify would not crash

What happened

Rust binary crashes the first time I run it after compilation. All subsequent invocations are working as expected. Only happens with the fsevent, the poll watcher works fine. I understand that this might be a MacOS thing, but maybe you can suggest some ways to debug.
