Description:
------------
a switch() statement testing a string offset, like
'switch($string{0})', crashes after executing the
matching case or default block. this only happens
if there is at least one case. workarounds: assign
offset to another variable first, or put it in
quotes like "{$string{0}}".
This breaks a lot of PEAR code, btw.
Reproduce code:
---------------
$x = 'abc';
switch ($x{0}) { default: print "default - works\n"; }
switch ($x{0}) { case 'a': print "case 'a' - bus error\n"; }
print "done\n";
Expected result:
----------------
default - works
case 'a' - bus error
done
Actual result:
--------------
default - works
case 'a' - bus error
Bus error
--------------------
