--- Comment #2 from Peter Wu <peter at lekensteyn dot nl> ---
GCC 6.2.1 is still affected by this. In C99 we can get away with flexible array
members, but this feature is unfortunately not defined in the C++
specification.

The idiom with an array of length 1 is quite common, is it possible to detect
that situation and relax the boundaries?
