Summary

0002156: Compile fails on unreachable code

Description

The following is legal, if somewhat nonsensical, PHP code (the real-life case was someone temporarily disabling a chunk of code that wasn't working properly):

<?php
for ($i = 1; $i < 10; $i++) {
continue;
print $i;
}

It runs fine in interpreted mode, but the compiler bombs out with the following error:

[11:37:26.958] java.lang.IllegalStateException: Location[null:0]'$i' is not analyzed.
