These were found with the help of -Wdangling-reference, which is
new in GCC 13.
The one in qtpaths.cpp is a false positive: parseLocationOrError()
returns a reference, so there's nothing for the full expression to
destroy. Moreover, it returns a reference to a static object, so
there's no destruction inside the function either.
The other two aren't, but are also harmless. QDBusMessage::arguments()
and QVariant::toList() return a stored QVariantList by value, so
QList's COW mechanism means at() returns a reference that will not be
destroyed. However, the compiler has no way of knowing that. And
since it depends on the implementation details, change the code to
not depend on that.

This is part of a series of patches deprecating implicit conversions
of QAtomic<T> variables to T.
Use relaxed atomic loads and stores on the 'isDebugging' variable. The
old code used the implict conversions to and from int and therefore
loadAcquire/storeRelease. Here, the int is the only value, it's not
guarding the construction of any other data, so relaxed loads and
stores suffice.
A further optimization would be to make the initial value of
isDebugging 0, to send it into the BSS instead of the TEXT/DATA
segment, but seeing as this is just compiled in for the auto-tests,
this patch leaves that particular change for another round (or never).

QVector = QList, and QList::iterator isn't a pointer, but converts

pointers. In preparation for deprecating conversions between them,
adjust this code by "converting" explicitly when needed.

If more than one signal parameter required conversions (e.g. 2

Found with valgrind after the QtApplicationManager started crashing
weirdly when built against Qt 6. The same code is in Qt 5, but it
just works fine there: I guess the reallocation strategy in QList is
different there, so we never have to reallocate the list.

The pre-existing overload passes an int, but this can mean the
descriptor gets truncated in compilations where the descriptor
is 64-bit.
The old overload with int is visible when querying the metaobject system
so string-based connects still work as before, and connecting to it will
produce a deprecation warning in the output.
At the same time the PMF-based connect will, on recompile, pick the
QSocketDescriptor overload. As an added improvement it also comes with
the notification type, removing the need for separate slots where the
code would be mostly shared anyway.
The QSocketDescriptor type can be implicitly converted to and from
qintptr to ensure existing code still compiles. It can also be
constructed from Qt::HANDLE on Windows.
In this same patch I also update the existing string-based connects in
this module, which then includes updating the parameters for some slots
as well.
[ChangeLog][QtCore][QSocketNotifier] Added
QSocketNotifier::activated(QSocketDescriptor, QSocketNotifier::Type).
This replaces the activated(int) signal which in 64-bit environments
could truncate the socket descriptor. If you use "activated" with the
string-based connect() then you need to update the parameter type of the
signal and slot if it had one. If you use it with the pointer to member
function based connect() then all you need to do is update your slot's
parameter type if it has one. If you need to compile your source code
with multiple versions of Qt then connect() to this function using
pointer to member function and update the slot's parameter type if
needed.
