[Bug c++/28220] New: Segfault in top-of-tree development gcc


While working on a report for a different bug, I mistyped the command line and
triggered what looks like a separate bug.  Here is how to reproduce it:

$ gzip -d bug.h.gz
$ touch bug.gch
$ ./cc1plus bug.h -fpreprocessed -o bug.s -quiet bug.gch
bug.gch:1: sorry, unimplemented: inter-module optimizations not implemented for
C++
Segmentation fault (core dumped)

I will attach the bug.h.gz file and a typescript of the gdb backtrace.
