Hi Solar, all,

The „tmp_ptr != base_ptr“ bounds check was originally added to the
_quicksort() function, but is not needed anymore in glibc 2.39 because
the old fallback to quick sort (the _quicksort() function) has been
completely removed and replaced by a fallback to heap sort.

Note, just in case: we have not reviewed the implementation of this new
fallback to heap sort.

Thank you very much for your kind words!

With best regards,
