I could not reproduce the bootstrap failure at -O3 on x86_64. I used --with-build-config=bootstrap-O3 . Maybe this is an arm (32?) only issue.
It looks like it is only reproducible with ILP32. And reported as https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111435 now. And I have a fix.
Thanks, Andrew
Thanks, Andrew
