On lines where the sizeof operators are.

Nothing serious.
Bug is invariant of any project settings.

i can be anything: static, non-const, declared in for loop, or only known at runtime and the bug is there, as long as a vla array is used with a variable.

int main( void )
{
const size_t i = 5 ;
char array[i] ;
const size_t size = sizeof( array ) ;
printf("%zu\n" , size ) ;
printf("%zu\n" , sizeof( array ) ) ;

return 0 ;
