Any chance you could comment on fluxsort[0], another fast quicksort? It's stable and uses a buffer about the size of the original array, which sounds like it puts it in a similar category as glidesort. Benchmarks against pdqsort at the end of that README; I can verify that it's faster on random data by 30% or so, and the stable partitioning should mean it's at least as adaptive (but the current implementation uses an initial analysis pass followed by adaptive mergesort rather than optimistic insertion sort to deal with nearly-sorted data, which IMO is fragile). There's an in-place effort called crumsort along similar lines, but it's not stable.
I've been doing a lot of work on sorting[2], in particular working to hybridize various approaches better. Very much looking forward to seeing how glidesort works.

The function is trying to get the median, which is not defined for an empty set. With this particular implementation, there is an assert for that:

Unrelatedly, but from the same section:
> Fixes are trivial, access the nth element only after the call being made. Be careful.
Wouldn't the proper fix to do the nth_element for the larget element first (for those cases that don't do that already) and then adjust the end to be the begin + larger_n for the second nth_element call? Otherwise the second call will check [begin + larger_n, end) again for no reason at all.
