Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.
Unfortunately this is not reproducible when compiling with -save-temps or when
using the preprocessed file, so I can't reduce it.
