--- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> ---
Uros, can you help me with this annoying wrong-code?

I suspect the back end could be also involved because it happens only for long
double and I didn't see anything special for long double in builtins.c

(if isn't clear enough, the expression in Comment #1 or #2 evaluates to -nan
instead of 0)
