Apparently, Tobias was faster in reducing the reproducer than myself. With the
fix by Tobias (I checked r265248) all of our code including testsuites with
different sets of flags works again. Thanks for the quick fix! Incredible job!

There is also: r265171 & r265175

50:50 me and Tobias - I look forward to your reduction.

First (long) reproducer

This is a first "complete" reproducer. I will boil it down now.
