The problem is the verifyConstExpr<>() line involving the ~ operator.
The result as an integer is a value that can no longer be represented
in an int. This is known at compile time and thus template deduction,
which only has an int to match against, fails.
To fix, use an unsigned int as the first template argument of
verifyConstExpr<>().
Clang's error message for this is really sub-optimal, cf.

When using __LINE__ to construct unique names, use of Q_STATIC_ASSERT

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.

The existing tst_qgetputenv shows that qputenv with an empty value
doesn't lead to the same result on Windows and on Unix, and there was
no way to fully delete an env var on Unix (which is needed for some
env vars where not-set and empty are different, such as TZ,
see `man tzset`).
This is also why qglobal has qEnvironmentVariableIsSet() vs
qEnvironmentVariableIsEmpty(), on the getter side.
Qt4's ifdefs around unsetenv in qapplication_x11.cpp show that this is
needed within Qt too (although this particular startup notification code
has to be re-imported into Qt5 still).

The current implementation of qIsNull only returns true if the value is

QPointF::isNull, where QPointF(-0, -0).isNull() will return false.
There doesn't seem to be a reason why the function exhibits this
behaviour (-0.0 is not accounted for in the unit tests), and for the
case of QSizeF::scale it causes a bug: qIsNull is used to check for
division by 0.0 before it proceeds, which fails in the case of -0.0.
