From 16e970aa81131259bed3a7b4bf119ed457ee9183 Mon Sep 17 00:00:00 2001 From: Edward Welbourne Date: Tue, 11 Jan 2022 15:01:22 +0100 Subject: Fix an assertion failure in massageAdjustedDateTime() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The QDateTimeData &d it's passed is a copy that's about to be modified; before we do so, we haven't detached so its internals have a ref-count of two, contradicting an assertion in the non-const Data::operator->(); so just directly access d.d->m_timezone, since we know that spec == TimeZone implies !isShort(). Added test that triggered the assertion and now doesn't.
