This commit looks too simple to be faulty. It must trigger a failure somewhere else.
It's happened before, quite often. The commit might be right, but it also might not (the lack of tests is a bit disturbing). Just counting by the number of lines changed isn't a good way to judge whether a commit is a likely candidate for a regression.
That native CRT libraries fix the problem is probably good enough confirmation that the bisect is accurate.
