Hello, and thanks for quick reaction.
I try to isolate this bug, and to make a reproductible test case, but it
seems
to be very difficult.
So, after more investigating i found some issues:
1. I suppose this bug is more related to script format itself, very very
strange.
For example:
I run the folowing script:
<?
error_reporting(E_ALL);
ini_set('display_errors','On');
require_once 'base.php';
$S =
'insert into TD_RENT
(
ID,
FDATE,
FTIME,
HOUSE_ID,
PERIOD_FROM,
PERIOD_TILL,
STATUS_ID,
PAYMODE_ID,
AMOUNT,
PERSONS,
AGENT_NAME,
AGENT_PHONE,
AGENT_MAIL,
AGENT_COUNTRY,
NOTE
)
values
(
next value for GS_UNIVERSAL,
current_date,
current_timestamp,
?, ?, ? - 1, 5, ?, ?, ?, ?, ?, ?, ?, ?
)
returning ID';
$P = array("100", "2011-03-12", "2011-03-31", "1", "2850.00", "1", "A",
"asdasd", "asdasd", "asdasd", "WEB");
$Q = DBQuery($S, $P);
?>
If i leave it intact hang appear. If i declare $S in one line, deleting
some
"tab" chars error dissapears.
Next, if I include directly content of base.php to make a test case,
leaving $S
as declared here, error disappears.
Also, if i rename base.php to any other name, for example mybase.php,
untouching
$S, error also dissapear, hwen i turn back, error appears, true
mistical.
So, I'm affraid i can't make a reproductible test case in 10-20 lines
:(
Maybe it is related to engine/parser, not function call_user_func_array,
really
don't know.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

Description:
------------
After upgrading to v. 5.3.5 and executing code like in test script php
hangs.
Chrome browser says: (net::ERR_EMPTY_RESPONSE): Unknown error.
Hangs occurs when I raise an exception in database trigger.
Raised exception from database appear in logs.
But any error related to call_user_func_array are not presend in the
logs.
When SQL statement executes without exeption, there is no hang.
In prior versions 5.2 i didn't meet such hangs.
Test script:
---------------
$this->Cursor = call_user_func_array('ibase_execute', $this->Params);
Expected result:
----------------
Run properly, without engine hangs
Actual result:
--------------
Chrome browser says: (net::ERR_EMPTY_RESPONSE): Unknown error.
