In fact, we have a local modification in our tree (different from the
one I recently suggested) where we default to using %ebp when inside a
frameless function, and inside a DLL. This is a heuristic way to handle
all those highly optimized functions for which prologue analysis cannot
be used. Short of implementing support for MS symbol info, this is the
only way we could get the backtrace of most threads. This is a hack I
didn't submit because it's a bit crude, and it only exchanges certain
failures for others - but we have found in practice that this was the
right choice for us. I can certainly post it too, if you are interested.
