With the current implementation, the QXcbConnection::m_focusWindow
was holding a dangling pointer during the focus transition from a
dying modal window to other modal window.
1) QXcbConnection::m_focusWindow holds a pointer to A;
2) A is closed;
3) relayFocusToModalWindow B;
=> m_focusWindow now points to a dead window.
4) We get a reply back from WM in a respone to
relayFocusToModalWindow (_NET_ACTIVE_WINDOW)
=> m_focusWindow now points to a valid window.
The fix is to update m_focusWindow to nullptr, when the current
focus window was destroyed and the new focus window has not been
set yet by WM.
This patch actually solves a more general case - whenever we get a
focus-out event, we should set m_focusWindow to nullptr. It is ok
for none of the windows to be in-focus while focus transition is
happening. The focusInPeeker will make sure to "optimize out" (when possible)
this no-window-in-focus state, and GUI won't be bothered by this
extra event. This is how things were working before relayFocusToModalWindow
was introduced. Having a focus-relay mechanism in-between is ok,
but it should not have changed the original behavior.

that case, we'd miss adding the -std=c++11 or -std=gnu++11 option to the

Some compilers are known to complain about this with a warning. GCC
complains about const on return values on -Wignored-qualifiers (enabled
at -Wextra), so it's not too much of a jump to assume that others do
too. Besides, this is not Qt Library API policy. As maintainer for
QtCore, I'm exercising my prerrogative in specifying certain unspecified
parts of the coding style, like I've done for constructor initializer
lists.
Since all the classes involved are exported (including QVector, through
derived classes), we can't remove the qualifier until Qt 6, since there
are compilers known to encode the qualifier in the mangled name
(suncc). I'm not introducing #ifdef to silence unknown compilers unless
we get an actual complaint.

Unix mmap(2) system calls do allow for mapping beyond the end of the
file, though what happens after you try to dereference the pointers it
gives is unspecified. POSIX[1] says that implementations shouldn't allow
it:
The system shall always zero-fill any partial page at the end of an
object. Further, the system shall never write out any modified portions
of the last page of an object which are beyond its end. References
within the address range starting at pa and continuing for len bytes to
whole pages following the end of an object shall result in delivery of
a SIGBUS signal.
However, Linux allows this in read-write mode and extends the file
(depending on the filesystem).
Windows MapViewOfFile never allows mapping beyond the end.
