Some of Rust proc-macro tests cause compiler to crash #614
Description
Failing tests:
- tests/ui/proc-macro/meta-macro.rs
- tests/ui/proc-macro/meta-macro-hygiene.rs
They both crash when calling free when rustc is linked with wild:
--- stdout -------------------------------
Def site: /home/mateusz/Projects/rust/tests/ui/proc-macro/auxiliary/make-macro.rs:7:9: 7:56 (#3)
Input: TokenStream []
Respanned: TokenStream []
------------------------------------------
--- stderr -------------------------------
free(): invalid pointer
------------------------------------------
It's not a crash in the test binary, but a crash inside stage1 rustc executable, likely making the debugging harder.
