Confirmed for 4.7.0 20120218 (experimental).

Reduced example with added information:

//----
#include <iostream>

#define FUNCTION_NAME __PRETTY_FUNCTION__

#define TRACE_FUNCTION(I) { std::cout << this << "->" << FUNCTION_NAME << "; i
= " << I << std::endl; }

struct A {
  int i;
  A(int i) : i(i) { TRACE_FUNCTION(i); }
  A(const A& rhs) : i(rhs.i) { TRACE_FUNCTION(i); }
  A &operator=(const A& rhs) { i = rhs.i; TRACE_FUNCTION(i); return *this; }
  ~A() { TRACE_FUNCTION(i); }
};

struct Y {
  A e1[2];
};

int main() {
  try {
    Y y1[1] = { {{1, (throw 0, 2)} } };
  } catch (int) {
  }
}
//----

Observed output is:

0x22fd60->A::A(int); i = 1

It does not happen when the local array y1 is replaced by a non-array Y.
