Bug#260747: g++-3.4 miscompiles code

[Daniel Schepler <schepler@math.berkeley.edu>]

I found the cause of this error: for some reason the global destructor
for idl_filename is being called twice.  I've attached a small test
case which trips the same bug; when compiled with g++-3.3, it produces
no output, but when compiled with g++-3.4, it outputs an error
message.

#include <iostream>

class Foo {
  public:
    Foo() { destroyed_ = false; }
    ~Foo() { if (destroyed_) std::cerr << "Destructor called twice!\n"; destroyed_ = true; }
    void nop() { }

  private:
    bool destroyed_;
};

Foo bar;

int main() {
  bar.nop();
  return 0;
}

extern Foo bar;
