You forgot -Wall -Wextra, or at the very least -Wall.  It probably will
help you find this problem., too.

-g2 is the default, and -maltivec is implied by -mcpu=power9.

Why do you disable assertions (-DNDEBUG)?

You didn't #include <altivec.h> in this scope, or you have undefined
__VSX__, or undefined something else; it is impossible for us to tell.

Always enable warnings, it helps.
