Description Giuseppe D'Angelo 2019-05-28 10:54:40 UTC 
Check if the code contains the constant "0x9e3779b9".

It's VERY likely someone is hand-rolling QtPrivate::QHashCombine / boost::hash_combine. Suggest to use those instead.

E.g. https://codereview.qt-project.org/c/qt/qtbase/+/263115/4/src/network/ssl/qsslerror.cpp#b367
