Description
After applying https://codereview.qt-project.org/#/c/259569/ to qtquickcontrols2 and running the test, I get the following crash:
SIGILL Illegal instruction

The issue can be reproduced with a simple Qt Quick application:
import QtQuick 2.9 import QtQuick.Window 2.2 Window { visible: true width: 640 height: 480 color: "#353637" }
And an even simpler C++ GUI application:
#include <QGuiApplication> #include <QColor> #include <QDebug> int main(int argc, char *argv[]) { QGuiApplication app(argc, argv); qDebug() << QColor("#353637"); return 0; }
The disassembly (the debugger is pointing to 0xa4a9ddba):
