qdisplayinfo_linux.cpp:50 is:
Q_GLOBAL_STATIC_WITH_ARGS(const QString, BACKLIGHT_SYSFS_PATH,
(QStringLiteral("/sys/class/backlight/")))
And the new Q_GLOBAL_STATIC implementation does:
[...] Holder() \
Q_DECL_NOEXCEPT_EXPR(noexcept(Type ARGS)) \
: value ARGS \
QStringLiteral is implemented using labda expression to get an anonymous
scope. But lambda sexpression are not allowed in noexcept.
Is that something we should fix in Q_GLOBAL_STATIC_WITH_ARGS ? or should we
jsut say that lambda expressions or QStringLiteral are not allowed in
Q_GLOBAL_STATIC_WITH_ARGS ?
