Using a proc_macro crate with more than 9 macros causes an ICE

[Bobo1239]

Minimal repro: https://github.com/Bobo1239/proc_macro_limit
proc_macro_limit defines 10 macros. cargo test results in an ICE (the test just contains extern crate proc_macro_limit). The ICE doesn't occur when any macro is removed.

edit: The ICE only manifest when using the proc-macro crate via extern crate proc_macro_limit;. So in the repro crate cargo build succeeds but cargo test fails with the ICE.

[Bobo1239]

@oli-obk My bad. Should have clarified that the ICE only occurs when actually using the proc-macro crate (extern crate proc_macro_limit;). So cargo build runs successfully but cargo test fails. I will update the initial post to include this detail.

[oli-obk]

Ah indeed. Unfortunately I'm running into stack overflows now :/
