It is easily reproducible, and

$ ../gcc-9.1.0/configure --prefix=$HOME/gcc9 --enable-languages=c,c++
--enable-libstdcxx-debug --disable-multilib
$ make profiledbootstrap

is enough. The same thing happens on Ubuntu bionic. Apparently
--enable-libstdcxx-debug and profiledbootstrap don’t play well
together. Either bootstrap or leaving out --enable-libstdcxx-debug
work. It’s just the combination of these two that breaks.
