These kind of divergences give reason to think that the sanitizers should be
further documented in the GCC manual. Another example is the range of supported
platforms: GCC's sanitizer could in principle support different ones (more?
fewer?) than Clang's.

I'm not saying that anyone should stop working on what they are doing to
implement this, but if a volunteer appears (Smagnet?) and wants to work on
this, why not allow them? Perhaps they can create better documentation than the
official one.
