Of course I ran make with "bootstrap" and with "profiledbootstrap". It still
fails to compile with a BOOT_CFLAGS set to -O3.

Since this is the section for reporting bugs and problems with bootstrap,
please explain to me why you changed the severity from major to minor. When you
tell me not to use the option at all I consider it to be broken and that is
surely not a minor problem!

I still fail to bootstrap with -O3.

Please explain why you close the report as being invalid.
