New Comment:
Understandably this might be a bit hackish to have use a global
variable
here, but perhaps thats preferable to what i'd consider a major
regression?
I attempted to patch this so I could just submit a patch here, but
unfortunately my c-fu and my understanding of PHP internals is lacking.

The sapi/cli/php_cli.c code will read forward when it see's a shebang
to the next line. The file is already seeked by the time the scanner
gets a change to look at it.
The zend_get_scanned_file_offset() doesn't know about this because by
the time the scanner is started the bytes are already long gone.
Short of a global variable I'm not seeing a clean way to fix this.

Scott, you worked on the re2c switch, any chance you can clarrify this
one?

Description:
------------
Starting in PHP 5.3.0, php no longer includes the shebang when
calculating the __COMPILER_HALT_OFFSET__.
Reproduce code:
---------------
#!/usr/bin/php
<?php
printf("__COMPILER_HALT_OFFSET__ is %d\n",__COMPILER_HALT_OFFSET__);
__halt_compiler();
Expected result:
----------------

-=[~]=- -=[Wed Jul 15]=- -=[13:37:38]=-
[a...@nighe]$ php test.php
__COMPILER_HALT_OFFSET__ is 94
-=[~]=- -=[Wed Jul 15]=- -=[13:37:39]=-
[a...@nighe]$ php-stock test.php
__COMPILER_HALT_OFFSET__ is 109
The latter answer in this case is correct, the shebang from the above
example is exactly 15 bytes with the newline, 109-15 == 94. So PHP is
not including the shebang in the __COMPILER_HALT_OFFSET__ calculation.
Actual result:
--------------
94!
