I wonder if it is filesystem related?  object files can contain areas
that are never written, and we rely on the operating system to fill
with zeros.

However, I think it's much more likely that "as" is writing some
uninitialised memory to file.  Please open a bug report at
http://sourceware.org/bugzilla/enter_bug.cgi?product=binutils and then
attach your .s source.
