I want to check back whether this issue still exists in PHP 7.2.20. The 7.2.19 release had some
serious issues with opcache and it may be that this is a side-effect of the same problems.

Hello cmb@php.net,
Results with OPCache on:
string(6) "2f6573" string(2) "ff"
Results with OPCache off:
string(6) "2f6573" string(2) "2f"

Please run the following variation of your script, and report the
results:
<?php
$in = "/es";
$out = substr($in, 0, 1);
var_dump(bin2hex($in), bin2hex($out));
?>

If removing opcache makes your problem go away then this may be a bug after all.
