It's very possible, but it's never safe to assume anything without testing.
Well then, what kind of test can I use to find out whether it's the same issue? Regression test? Any others?
A regression test should be run to find the patch the caused the problem. Once you've identified that patch, try reverting it and testing your 16-bit applications. If all work, then they all have the same problem.
