You mean a test case as described in
<https://gcc.gnu.org/bugs/minimize.html>?  The specific function this is
happening in is an internal helper function relying on global state of
Vim's regex engine.  I don't have a minimal runtime test case, let alone
a minimal piece of code to reproduce the problem.

I'll try to find some time to get either of those.  In the mean time,
I'll keep testing new GCC-5 uploads.
