The mailing list gcc-help@gcc.gnu.org would be a better place.

It may not matter.  As long as the crash happens when you use the
--save-temps option, then reporting the bug with the .ii file may be
enough.  However, it's true that if other people are unable to recreate
the problem then it may not be possible to fix it.

Sometimes this can indicate that there is a problem with precompiled
haders.  Do you know if you are using a precompiled header?

Do it anyhow if that is the only way.
