So the // program should nevertheless compile, but it should give a warning.) class A; // { dg-message "7:forward declaration of 'class A'" } A *a; // { dg-warning "4:'a' has incomplete type" } int main (int argc, char **argv) { delete a; // { dg-warning "3:possible problem detected in invocation of .operator delete."
