+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.
