Rebuilt and reloaded libraries on macOS only ever seem to provide symbols from the first library that was loaded

[mitchmindtree]

Tried many things to fix this so far:

• Tried dropping the cargo config after watch and reloading them on each call to Watch::package.
• Tried slugify-ing the timestamp within the filename.
• Checked that cargo is generating a new dylib on each reload.
• Checked that the library is actually different on each reload by printing the library's path.

It's almost like the symbol is being cached in global memory or something.

I think I am hitting this same issue and am attempting to solve it on my own fork -- any idea if there is a known fix/workaround?

It looks like we are already using the trick from nagisa/rust_libloading#59. Unfortunately, I still see the behavior you mentioned.

It could be that the problem is in my own code, though I am not certain yet. I will investigate in detail and write up a specification of the behavior I am currently witnessing.

I'm also hitting this issue but on a Flatcar os
