Yep, different bug.  The crash is due to an error in a parameter type not
resulting in TypeFunction::semantic returning terror.  (Or at least, that and
the fact it reaches code generation due to this bug.)  I swear I fixed this in
a pull request last year, but it must've been part of something that never got
accepted.
