https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71959 --- Comment #5 from Christopher Guckes --- I'm using a very ugly workaround, since I'm only working on a proof of concept. Can you comment on this post, once references are working? Many thanks for your time.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71959 --- Comment #3 from Christopher Guckes --- I've investigated a bit further. The problem seems to occur only if the routine is passed by reference. Maybe that helps you isolate the problem any further.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71959 --- Comment #1 from Christopher Guckes --- I replaced the iterator with an array but it still crashes. I assume it has something to do with the function pointers or the use of templates. Will investigate further.
