--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Yes the warning is correct here. Since from reading the code nVertex starts at
4 (4*2) and can increase.
The issue is here is 8 is the min number of elements for the source but in C,
it is also the max number of elements too. Even if you use 1 it is max of 1
(but GCC has an exception based on the -fstrict-flex-arrays option).
