Please submit a full bug report,
with preprocessed source if appropriate.
See <https://gcc.gnu.org/bugs/> for instructions.
Code example is attached, will try to boil it down more to the essentials.
I believe that it should have been introduced somewhere between r253992 and
r254916. 
Just unpack the example and do 'make'.
