...with preprocessed source if appropriate.

Can you provide that?

Isn't a link to the source code sufficient? You can generate your own, if you
want.

Never mind.  I've actually already fixed this one.

No, links to other sites for us to download code from aren't sufficient.  What
we ask for is documented in https://gcc.gnu.org/bugs/#need, namely:

Please include all of the following items, the first three of which can be
obtained from the output of gcc -v:
    ...
    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).

One reason for this is so that when the site becomes unavailable or the
information on it changes the bug report can still be properly analyzed.
