The broken ld has been discussed already, this is a bug in ld that I
fixed some days ago - but we also changed glibc again.  So updating
might fix your problem.  If not, please write a small program that
shows the behaviour and send it here.

The problem is the usage of fileno and interaction of streams and files,
