Clang 19 -std=c++23 complained that ITERATIONS_PER_THREAD was
captured, but not used, so 668d81f73a5c2f4ec14764d1892f2eaf6494c0f1
dropped it, after making the variable constexpr.
Picking that change back to older branches, we found that MSVC
(14.29?) complains that it's _not_ captured anymore:
tst_qpointer.cpp(491): error C3493: 'ITERATIONS_PER_THREAD' cannot be implicitly captured because no default capture mode has been specified
To appease both compilers, and cover the maximum range of C++ standard
editions, use implicit [&] capture, which should work everywhere.
Not picking to 6.5, because the cherry-pick of
668d81f73a5c2f4ec14764d1892f2eaf6494c0f1 already had to make that
change in order to pass CI.
Pick-to: 6.10 6.9 6.8
