[issue44878] Clumsy dispatching on interpreter entry.

[Mark Shannon]

Mark Shannon <mark at hotpy.org> added the comment:

I'm somewhat surprised by that. After all, the only change in control flow was the change from a break to a goto in exception handling.
I would have expected PR27726 to have made much more difference.

There are a few possibilities, including:
1. It's just a random fluctuation from tiny changes in alignment.
2. MSVC aligns loops, but not switches, or vice-versa, and that makes a systematic difference.

I suspect that it is (1), but this is a bit worrying nonetheless.
