Calling parent::__construct() crashes compiled program.

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Compile attached test-parent.php file with "phc -c test-parent.php -o
test-parent"
2. Run ./test-parent
3. Result: "SIGSEGV received!"

What is the expected output? What do you see instead?

Expected output (using "php test-parent.php"):

A constructor: B constructor: B object

What version of the product are you using? On what operating system?

From SVN, revision 2535.

OS: Debian Etch.

PHP used in phc compilation: tried with 5.2.0 (same as Debian package) and
5.2.9.

Please provide any additional information below.

It happens in the Zend API, in zend_is_callable_check_func when trying to
use EG(active_op_array), quick look with gdb shows that the active_op_array
member of the executor globals struct has a NULL value:

(gdb) p ((zend_executor_globals *) (*((void ***)
tsrm_ls))[((executor_globals_id)-1)])->active_op_array
$3 = (zend_op_array *) 0x0

Thanks for the report.

We think this is because we're trying to lookup the class "parent". I think the
correct fix is further up the pass queue, so that the code generator never sees
"parent", but instead sees (in this case) "a", the parent class name.
