[previous] 0944 [next] [C] The label '%s' is inside the scope of an identifier with variably modified type.
Constraint violations REFERENCE - ISO:C99-6.8.6.1 The goto statement - Constraints

This is a constraint error

This 'goto' statement jumps backwards and enters the scope of an identifier with variably modified type.

Jumping into into the scope of an identifier with variably modified type from outside the scope of that identifier is not permitted.

For example: 


/*PRQA S 1051,2001,2015,2017,2200,2201,2212,3120,3220,3227,3408 ++*/

void foo(int n)
{
    if (n < 100)
    {
        int a[n];       /* "a" is declared with variably modified type */
        a[0] = 1;
lab1:   a[1] = 0;
        a[0] += n;
    }

    if (n == 0)
        goto lab1;      /* Message 0944 */
}
