However, the cygwin-gcc is not a 3.3 and is has some bugs. Since the cygwin
dll source is in large parts c++ i thought some bugs of the `wrong-code'-kind
could creep into cygwin1.dll. Since i do not know the innards of cygwin
very well i recompiled the dll just to be sure, but i dont really know if 
this is necessary. I send a small code example that fails with the gcc-3.2
that demonstrates a problematic construct. This is a known gcc-problem and
doesnt strictly belong here, but perhaps someone reading it would be able
to say if this is relevant to the cygwin-dll. Likely that all this has nothing
to do with the original message.

Greetings - Rasmus

// bug-code: gcc-3.2 wont call destructor of D
#include <stdio.h>
struct D {
  D () { printf ("D ()\n"); }
  ~D () { printf ("~D (this=%p)\n", this); }
};
void use_D (D d) { }
const D make_D () {
  return D ();
}
int main () {
  use_D (make_D ());
}
// end of code
