    selftest: Work around GCC 4.2 PR33916 bug by optimizing the ctor [PR894=
94]

    GCC 4.2 due to PR33916 miscompiles temp_dump_context ctor, because it
doesn't
    zero initialize the whole dump_context temporary on which it runs the
static
    get method and during destruction of the temporary an uninitialized poi=
nter
    is deleted.

    More recent GCC versions properly zero initialize it and ideally optimi=
ze
away
    the construction/destruction of the temporary, as it isn't used for
anything,
    but there is no reason to create the temporary, static member functions=
 can
    be called without an associated object.
