Hi all,

The array "A a[1];" didn't call destructor automatically.
This following code explains itself.

I think maybe this is an exception handling bug on array type?
Thanks!

  1 #include <iostream>
  2
  3 struct A {
  4   A() {
  5     std::cerr << "Constructor\n";
  6   }
  7   ~A() {
  8     std::cerr << "Destructor\n";    // Error: Didn't show this.
  9   }
 10 };
 11
 12 struct B {
 13   A a[1];    // If I use "A a;", everything works!
 14
 15   B() {
 16     throw 0;
 17   }
 18 };
 19
 20 int main() {
 21   try {
 22     B b;
 23   } catch (...) {
 24   }
 25   return 0;
 26 }
