In newer versions of GCC there is also a lot more debug info and Dwarf-2
exception table data that didn't used to be there.  Stripping the dll and/or
building a compiler with SJLJ rather than dwarf exceptions might help, although
SJLJ trades off executable size for slower runtime.  (Badly; dwarf exceptions
only take CPU time when one is actually thrown, whereas SJLJ exceptions take
CPU time every time you enter or exit a try block.  Since exceptions are meant
to be exceptional conditions that only happen occasionally, this tradeoff is
probably worthwhile on desktop platforms where memory is not in short supply,
but SJLJ might still be better on embedded platforms where memory is so
critical that slower runtime performance might be the preferable option.)
