That's surprising, the code I touched is only ever supposed to run while
compiling one file in libsupc++, if I understand correctly.

Ah, well, perhaps it's one of the first built for stage1 libstdc++.
I admit to not digging much deeper.  ;-)

Would mangling the aarch64 builtins be a lot of work? Did other platforms break as well?

I've no idea on difficulty.  I've not yet checked other platforms.


This affects arm as well. The same ICE in mangle.c.
The arm and aarch64 mangling code is very similar...
