Do not automatically add a \n to all messages formatted by
qFormatLogMessage. Some backends require a final newline,
some don't, so it's best to only append it where it's actually needed.
The returned string will be null if the pattern is empty. This allows
to differentiate between the case that the pattern just didn't apply
(empty line is printed), and the case that qSetMessagePattern(QString())
have been called (nothing is printed).

as well as some nasty assembler rewriting to actually access them. The

This also covers qt_startup_hook (similar problem), and the Qt version

The result as an integer is a value that can no longer be represented

The problem was that the HolderBase destructor was getting called after
the contained type's constructor threw an exception, as is required by
RAII semantics (the base was fully initialized, so it had to be
destroyed). That was required because we want to return a non-null
pointer from operator() during destruction and return null after
destruction, to keep compatibility with Qt 4.
The solution is to only set the guard to Destroyed only if it is already
at value Initialized. This way, if the HolderBase destructor is run as
part of the stack unwinding, it knows that the construction did not
complete.
