if this is presented as _FORTIFY_SOURCE check, it should call that

I understand. I don't know much about -D_FORTIFY_SOURCE, honestly. I
hope the diagnostics provided by __chk_fail is good enough. And
well, then we really do have to explain in a comment where
__chk_fail is coming from ;)
The default error output is like:
I understand it's some sort of "standard" thus certainly I'm not going to insist, but I would like to see more clearly displayed the line number of the library assertion failing, see what I mean?

Thanks,
Paolo.
