And the crash would be "fresh", as close as possible to the real crash site. I'd think that this is how UseOSErrorReporting is supposed to work, leaving crash reporting up to the OS.

We had envisioned using a Windows API that was being added in maybe Vista to transmit the hs_err_pid file to WER.  I think that was why we decided to generate it.  Getting a real "fresh" crash site as you say would be an improvement for us as well.  I don't know how to get both.
