I don't think it is possible for this to cause a compilation error, due
to the logic that assures NDEBUG and MALLOC_DEBUG are set in a mutually
coherent manner. Is there some set of compilation flags that can cause
compilation to fail?

Yes, you're right: I had overlooked that the NDEBUG is mangled
basing on the value of the MALLOC_DEBUG. In principle, one can
later do something nasty with the NDEBUG that will broke the coherency
and this will result in the non-compilable code. Though it will
be rather easy to find out.

No, I was just digging through the code and (wrongly) assumed that
an inconsistency had been found.
Sorry for the noise. The PR can be closed.
