I'd be willing to bet something untoward has happened to /dev/zero; it's
supposed to be a magical character device that returns as many zeroes as
the reader desires, and I'll bet it's gotten erased and replaced with a
normal file, or just plain erased...

ld.so uses /dev/zero to clear its own bss (by mapping /dev/zero to the
proper pages).  The lack of any immediate mention in the manuals is
reprehensible.
