With -std=c++11 the assumption that this is compile time constant sized array
is bogus, std::max is constexpr only in -std=c++14 and later.  It doesn't
matter if your variable is const, it is still initialized at runtime, so char
array[LIM]
is a VLA and this ICEs because of the PR79993.

Confirmed on trunk/branch.  Works with c++14 (detail of std::max?).
