Description:
------------
PHP gives "unexpected T_ELSE" and "unexpected T_CASE" errors on valid code.  checked the code over with brace checker and dreamweaver 8 and older versions of PHP for correctness.
maybe it has something to do with the structure of my if/else/switch statements and my weaving in and out of the PHP interpreter.  The rest of my 40+ files are fine.  just these 2 give me errors in the same place consistently.

Reproduce code:
---------------
http://mmediap3.home.comcast.net/z/phpprob.zip  includes include files header.php and dbinc.php

you may need to execute a short script with header.php in it and a line to set $_SESSION['tid']=1; for tareports.php to output XHTML.
execute script from command-line. (executing this script just caused PHP to hang and not die this time (?!?))

Expected result:
----------------
error messaged about $_SERVER[REMOTE_ADDR] not being defined. and maybe some messages about some session variables not being defined, ad a lot of XHTML.
if $_SESSION[tid] is not defined, no XHTML.
and if the tables aren't defined on your box (MySQL sql script included), probably mysql errors.

Actual result:
--------------
older versions of PHP output XHTML (or hang).
C:\prj>php tareports.php
PHP Parse error:  parse error, unexpected T_ELSE in tareports.php on line 211
causes PHP crash with stack trace outlined below.

When I comment this else block out, it complains about the next else. when I comment *that* out, it complains about the case statement that comes next. sounds to me like the parser's in an odd state, or some pointer or piece of memory got mangled.

C:\prj>php userreports.php
PHP Parse error:  syntax error, unexpected T_CASE in userreports.php on line 285
which causes an Access Violation.
Actually, all errors cause an Access Violation in this debug version.
