Marc Mutz b1b0f42c97 tst_qtconcurrentrun: fix UB (uninit'ed values)
While doubleFunction's body is empty, it takes its argument by value,
which means copying. Copying an uninitialized double is a gray zone
(if you follow the partially-formed paradigma, it's UB; though the std
may allow it some types, most notably std::byte and uchar; probably
not double, though). Converting an uninitialized int into double is
most certainly UB.

Fix by initializing both d and i.

Found by GCC 11's -Wmaybe-uninitialized.

Pick-to: 6.5 6.2 5.15
