--- Comment #1 from Alexander Monakov <amonakov at gcc dot gnu.org> --- Sorry, I cannot reproduce this. I've built a cross-compiler from today's trunk via 'configure --target aarch64-linux-gnu && make all-gcc' (i.e. just to cc1plus, no binutils etc.) and it doesn't abort. If possible please add 'g++ -v' output, svn revision, and any other info that can help me reproduce the issue.
