 #include <stdio.h>
 char * memset2 (char v[],char ch, int n);

 int main()
 {
    char *v = "PaP Programar";
    char ch = 'A';
    int n = 3; 
    
   
    puts("abc");
    printf("A string alterada é: %s \n",memset2(v,ch,n));
    puts("ghdfj");
 }

 char * memset2 (char v[],char ch, int n)
    {
        int i;
        for (i=0; i<n;i++)
            v[i] = ch;
        return v;
    }

a variável v contem um ponteiro para uma região de memória da qual não podes alterar (a string "PaP Programar")

quando vais tentar atribuir o caracter ch à posição v[i ], tens o problema que referes.
