You snipped too much context.  If a piece of code isn't
able to deal with an allocation failure, it doesn't matter
where the allocation falure came from.  If a piece of
code is able to deal with allocation failure in some way,
that applies equally to allocation failures for malloc()
and VLAs, assuming of course that VLA allocation failure
can be detected, which I pointed out upthread that it
can in a conforming implementation, if the implementation
so desires.  The ability or non-ability of some piece of
code to respond sensibly to allocation failure has no
bearing on the point I was making.
