For this purpose it's usually enough to only have the function that contains the switch, even
if it cannot be run in isolation. The surrounding code (likely) does not matter. The code is only
needed to get an opcode dump and see the faulty transformation, a smaller test case can then be
reconstructed from there.

I'm really sorry, but I can't. I'm working on a backend for a music publisher and
we're talking about a huge project. When I find the time I'll try again to reproduce the
problem outside this project. It doesn't happen if I isolate the method so it could be hard to
pinpoint... :(

Can you please provide the (non-reduced) source code of the function that is failing? If you
can't publish the code, please feel free to mail to me directly at nikic@php.net.

I doubt it's specific to Windows. Likely just a regular opcache bug.

Indeed, disabling opcache fixed the problem. So is this a bug specific to 7.3 or the windows
version? Because I never had a problem with 7.2 and opcache enabled.

What if you disable opcache?
