------- Additional Comments From bangerth at dealii dot org  2003-10-27 18:08 -------
Andrew's code is close, but not quite valid. Here's a valid variant:
---------------------------------
#include <string>

extern "C" int printf(const char*,...);

struct a {
  a()  { printf("a::a\n");  }
  ~a() { printf("a::~a\n"); }
};

int main() {
  a a1;
  std::string x;
  switch(0) {
    case 1:
      {
        a a2;
        return 0;
      }
  };
};
-------------------------------------------
I can confirm the failure with a tree-ssa snapshot from 20031024.
