--- Comment #15 from amker at gcc dot gnu.org ---
Well, only thing suspicious that I can see, the memset function is a special
implementation and not from C standard library.  Basically it doesn't need to
follow the standard, which means the return value could be something else other
than the passed in pointer.  Though I doubt it would actually break the
standard.

So YuFan, could you help look into implementation of memset to see if it acts
as expected?

Thanks.
