This is deep in the middle of some extremely complicated template
instantiations; it's impossible to say anything without a stack trace.

This means it's probably a bug in codegen for debug info; it's still
experimental, so expect issues.  The line information is pretty
reliable, but generating type information isn't; I think I have a hack
in my tree that adds an early return to type info generation so I can
use -g for the line number info.
