Subject: make_and_run_test_nodes: avoid undefined behaviour
In code that looks like n[i] = v(&i), where v increments i, C leaves it
undefined whether the old or new value of i is used to locate n[i].
As it happens, gcc used the pre-increment value of i, but MSVC
used the post-increment value.
Fix this by inserting a sequence point to disambiguate the intended order.
