If you can point me to a proper bug tracker, I'd be happy to post there. I don't have Windows development env set up. but I am attaching a proof-of-concept patch, which abuses the m_bits field as a secondary key during the sorting phase to achieve a stable sort with a generic Quicksort. Under glibc, chdman output is the same, because glibc qsort() is stable as you mentioned above. I expect that on Windows, qsort() is not stable and the output will change. Could you please check if you have time?
