--- Comment #6 from Thiago Macieira <thiago at kde dot org> ---
Suggestion: add a function to libgcc to be called instead of
__cxa_throw_bad_array_new_length when exceptions are disabled. That function
can be a mere two instructions, but it provides two advantages:
* no need to stream something into LTO
* allows post-compilation tools to know what's happened (Valgrind, debugger=
s,
etc.)

I don't know if this is an acceptable solution, but I thought I'd make the
suggestion.=
