Confirmed in recent cvs. It only happens with a default: block before
which there is an applicable case ending in a break; statement.
<?php
$line = '*';
switch ($line{0}) { // crashes also with $line[0]
case '*';
echo '* RAN!';
ob_flush();
break;
default:
echo 'Default RAN!';
ob_flush();
}
?>
This results in '* RAN!Segmentation Fault'. :(
BTW, I discovered this bug because it breaks Wakka.

This bug is very similar to #26281, in fact, it's probably the same.
