This happens to work but I suspect it's only by accident.  When

the number of elements in the VLA GCC gets into infinite recursion.
(I opened bug 69516 with a test case).  The same error in a non-
constexpr function causes a SEGV at runtime (this is also
a regression WRT 4.9.3 -- I opened bug 69517 for it).


FWIW, the patch I posted today should cure all those infinite recursions.


Sounds good, and thanks for the heads up.  I volunteered to add
a louder warning for the VLA initialization and I hope to find
some time to work on it as early as next week.
