--- Comment #10 from Victor Porton <porton at narod dot ru> ---
I notified the Ahven author.

However, the bug is quite weird: Isn't linking with a library just no-op if no
functions from the library are called? I wonder how the bug may depend on
linking with it. So I feel it is a GCC bug.

I also did a quick search in Ahven sources about interrupts and signals and
found nothing. So how can it be an Ahven bug?
