Hi,

This bug complains about undefined behavior when user closes file
descriptor. This is again patch or close case.

We could check this by asking kernel if descriptor is valid.

Comments?


	* libio/freopen.c: Check if file descriptors are open.
Couldn't this be done in a pre-load checker as well so that conforming code doesn't pay the checking penalty?
