--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
I don't see the ICE with my cross-compiler and the stack trace doesn't
correspond to the latest sources (there's no call to error() at
gcc/config/aarch64/aarch64-builtins.c:1588; a call to error_at() that replaced
the error() in r12-2088 is on line 1601) so it's hard for me to say what's
going on.

What is the bootstrap problem?

Christophe, I thought you had successfully bootstrapped and tested the patch on
aarch64?
