new_op_array = zend_compile_string(&pv, string_name TSRMLS_CC);



line 1175 of main/zend_execute_API.c



this never returns handle of opCodes to compiled php-string nor null

but dies directly.

WRONG FATAL ERROR....

  wrongAssigment() = FALSE;

 

?>

Errors parsing lint-test1.php



LINT is telling is a PARSE ERROR...

LINT SHOULD not execute code but only check syntax, or not?

That's a runtime fatal error, not a parse error, and hence results in

the script execution halting, as per the second note on the eval()

manual page.

>From manual page: http://www.php.net/function.eval#Return Values

---



eval() shoud return FALSE in case of parse error.



In this example crashes completely with a fatal error, executing

a dead portion of code. A return should terminate the eval script as
soon

as is encountered.



Seems to be a compilation problem.

Test script:
---------------
<?php



  $return = eval( 'return TRUE; /* should never come here */
WrongAssignment() = 1234;' );



?>

Expected result:
----------------
$return should be FALSE as there is a PARSE ERROR (from manual: "If
there is a 

parse error in the evaluated code, eval() returns FALSE and execution of
the 

following code continues normally.").



But the parse error is not detected and in this case $return should be
TRUE,

as the first block simply returns TRUE and the rest is dead-code.

Actual result:
--------------
Fatal error: Can't use function return value in write context in 

/Users/dynamicplus/eval-demo.php(3) : eval()'d code on line 1
