New Comment:
I've been running up against this blasted bug for some time in my test
scripts - can't test for Exceptions without hard coding it. Anyhow, I
just peeked under the hood and think I've got it squashed.
file: ./ext/standand/basic_functions.c line 1984 - 1985 reads:
if (call_user_function_ex(EG(function_table), NULL, *func,
&retval_ptr, count, func_params, 0, NULL TSRMLS_CC) == SUCCESS &&
retval_ptr) {
COPY_PZVAL_TO_ZVAL(*return_value, retval_ptr);
The cause of the bug seems to be the "&& retval_ptr" as an exception
doesn't appear to return the same. It works when you adjust it to work
like call_user_func() where it can succeed even if retval_ptr doesn't
exist and/or is false.
Modified ./ext/standand/basic_functions.c line 1984 - 1985 replaced to
1984 - 1984:
if (call_user_function_ex(EG(function_table), NULL, *func,
&retval_ptr, count, func_params, 0, NULL TSRMLS_CC) == SUCCESS ) {
if (retval_ptr) {
COPY_PZVAL_TO_ZVAL(*return_value, retval_ptr);
}
I compiled it and ran the test that Benjamin posted on the 16th of
Augest. I did get the correct output (11, 17, & 23).
The modified file is available from:
http://www.domain51productions.com/php/basic_functions.c
In the latest 5.0.X CVS, these lines have moved to 1991 - 1992.
Note: If there's another way to handle submitting a patch, just let me
know.

The fixed code:
<?php
function test($test) {
throw new Exception("This is a " . $test);
}
call_user_func_array("test", array("test"));
?>
