This static is unique per function signature, not per function (name/dll). So if you have `void doFoo()` and `void doBar()` that you import, you'd create two `LazyImport<void(*)()>`, but they would return the function that was first resolved with `get()`. I think you could fix this if you resolve the function in the constructor and only save the pointer to it (most importantly it would remove this `static`). https://github.com/llvm/llvm-project/pull/199983 _______________________________________________ lldb-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
