Is this a bug in some C compilers?

No, you're thinking about it the wrong way around.  A (non-strictly)
conforming program is simply one that is acceptable to SOME conforming
implementation (one wonders, why bother to define such a critter; it
was essentially a political decision).  However, conforming
implementations must meet numerous requirements other than simply
accepting all strictly standard-conforming programs.  Section 2.1.1.3
states:  "A conforming implementation shall produce at least one
diagnostic message ... for every translation unit that contains a
violation of any syntax rule or constraint."
