I usually just add -save-temps, but your invocation will work as well.

When you preprocess a source file, it will automatically include the
needed headers, so sending them isn't necessary.  Just the .i from the
affected file will do, in this case.  If there were a linking bug or
something, the entire source would be needed, but since this is just
an optimisation error being triggered by one file, you shouldn't need
to send the whole thing.
