Can you make small test for it? easy to keep away from this issue, but it should be fixed.

Hi!

It seems that a regression bug has been recently introduced in the TracePoint API (maybe after changeset r45758). byebug's test suite works against 2.0 and 2.1, but segfaults against ruby-head. See https://travis-ci.org/deivid-rodriguez/byebug

Segfault occurs in https://github.com/deivid-rodriguez/byebug/blob/master/ext/byebug/byebug.c#L252, I'm guessing the method ID provided by the TracePoint API is nil, so the SYM2ID call fails.

I'm sorry I'm not currently able to properly investigate this.
