Comment (by raimue):

 Linking my findings from last April:
 https://lists.macosforge.org/pipermail/macports-dev/2016-April/032891.html

 The problem appears to be that a bug in libedit that was fixed, but
 CPython actually relied on this bug to work properly. If this bug does not
 occur with CPython on other platforms using libedit, it might be worth a
 shot to scrub the whole `#ifdef __APPLE__` parts for readline/libedit
 handling. This use of `#ifdef __APPLE__` seems to be meant as "using
 libedit as shipped by Apple", but this is clearly wrong and a bad way to
 match this condition.
