ID: 20927 User updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] -Status: Feedback +Status: Open Bug Type: PostgreSQL related Operating System: Red Hat Linux 8.0 on Intel PHP Version: 4.3.0RC2 New Comment:
Hi, I've tried the following versions of libpq: 7.2.2 7.2.3 7.3.0 They all exhibit the same behaviour. The default version that comes with RH8.0 is 7.2.2. Thanks, David. Previous Comments: ------------------------------------------------------------------------ [2002-12-11 10:35:04] [EMAIL PROTECTED] Uhmm I should read better... What versions of libpq do you use with 4.1.2 and 4.2.x? ------------------------------------------------------------------------ [2002-12-11 10:34:38] [EMAIL PROTECTED] Then how do you explain the crash in Apache 1.3.27? It is a PHP bug for sure, because changing PHP versions is the only thing which makes it go away. ------------------------------------------------------------------------ [2002-12-11 10:32:10] [EMAIL PROTECTED] It crashs with PHP 4.2.2 because it runs in Apache 2. The PSQL lib ist most probably not thread safe. ------------------------------------------------------------------------ [2002-12-11 09:55:43] [EMAIL PROTECTED] I disagree. The bug *IS* in PHP, not libpq. The reason I assert this is as follows: - I tried Apache 1.3.27, 2.0.40 and 2.0.43 with libraries from PostgreSQL 7.2.2, 7.2.3 and 7.3, and PHP 4.2.2, 4.2.3 and PHP 4.3.0RC2. ALL combinations crashed reliably. With PHP 4.1.2, I am *unable* to get a crash. Something in PHP is corrupting memory, and later on, malloc() is failing. I use the same libpq library with Perl and Tcl, and have never yet had a segfault. For more info, here's a stack trace for Red Hat 8.0 with Red Hat's version of Apache (2.0.40) and Red Hat's PHP (4.2.2). Program received signal SIGSEGV, Segmentation fault.

For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. The crash is the fault of PostgreSQL and not that of PHP. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
