Hi!
I randomly get the following compilation error when developing a proc-macro:

error: /path/to/rust/project/target/debug/deps/libmy_proc_macro_crate-bed23c204003db91.so: undefined symbol: __rustc_derive_registrar__b0028b8f317d7b045e78ce5c492cc011_18
 --> src/main.rs:3:1
  |
3 | extern crate my_proc_macro_crate;
  | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Running cargo clean fix (temporarily) the issue.
Thanks to fix this issue.
