--- Comment #9 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
Please see https://gcc.gnu.org/bugs/#need for the things that
are required for a bug report.

Specifically, 

the preprocessed file (*.i*) that triggers the bug, generated by adding
-save-temps to the complete compilation command, or, in the case of a bug
report for the GNAT front end, a complete set of source files (see below).
