  That's because stdout is already closed by the time your dtor runs.  I
stepped right into it, it does the printf call but somewhere down in the dll
it checks the flags field in the stdout FILE object for read/write and finds
it's not open for either, so it's at eof.  Grep 'cantwrite' if you really
want to find it.

  Anyway, your dtor is called.


    cheers,
