today's git does not compile

Nicely done!  Thanks for taking the time to do the full-on gcc bug
report with .i file.

If at some point in the future you want to ascend to the next
level of gcc bug reporting awesomeness, read up
on delta debugging, an easy technique for automatically
reducing the .i file to (nearly) the smallest possible
input file that causes the crash.

Or don't; it's an easy next step for the gcc professionals,
given what you gave them.
