#19964 [NEW]: Fix for bug 19482 missing from latest snapshot
From: [EMAIL PROTECTED] Operating system: Red Hat 7.3 PHP version: 4CVS-2002-10-17 PHP Bug Type: PCRE related Bug description: Fix for bug 19482 missing from latest snapshot Bugfix for #19482 against php-4.2.3 fixed the segfaults but I had to upgrade our PHP to 4.2.4dev because bug #19829 was nailing us. After upgrade, the segfaults reappeared. Checking latest version from snaps.php.net (200210171200) i noticed the fix for #19482 has disappeared from php_pcre.c Wondering if this was intentional or not. If not intential i will attempt to generate a backtrace of the more recent segfault. For now i have re-patched the php4-STABLE-200210171200.tar.gz version with the fix from 19482. -- Edit bug report at http://bugs.php.net/?id=19964&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=19964&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=19964&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=19964&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=19964&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=19964&r=oldversion Not developer issue:http://bugs.php.net/fix.php?id=19964&r=support Expected behavior: http://bugs.php.net/fix.php?id=19964&r=notwrong Not enough info:http://bugs.php.net/fix.php?id=19964&r=notenoughinfo Submitted twice:http://bugs.php.net/fix.php?id=19964&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=19964&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=19964&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=19964&r=dst IIS Stability: http://bugs.php.net/fix.php?id=19964&r=isapi
#19829 [Com]: form array variables get trimmed
ID: 19829 Comment by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Closed Bug Type: Scripting Engine problem Operating System: linux PHP Version: 4.2.3 New Comment: If this was not a large fix, is it possible for you to post what changes were required so they can be integrated into 4.2.3 until the next version is released? If you can do that it would be very (very, very ;>) much appreciated. Previous Comments: [2002-10-09 04:05:04] [EMAIL PROTECTED] This bug has been fixed in CVS. In case this was a PHP problem, snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. In case this was a documentation problem, the fix will show up soon at http://www.php.net/manual/. In case this was a PHP.net website problem, the change will show up on the PHP.net site and on the mirror sites in short time. Thank you for the report, and for helping us make PHP better. [2002-10-09 04:02:46] [EMAIL PROTECTED] i have a form with input fields declared like this: ie. form variables are returned in array 'p'. the problem is that returned values get cut their first four characters off. -- Edit this bug report at http://bugs.php.net/?id=19829&edit=1

Note sure if this will be useful, but if i edit main/php_config.h
(after running ./configure) and remove all LOCALE defines, here's a
backtrace of the segfault:

hello!
i have nearly the same problem...
i've wondered, that sometimes are segfaults in the error_log. i have
installed
the newest php (4.2.3) & apache (1.3.26) version.
now i have found a cause:
if this in the mail header:
From: ()
imp shows as sender. with the attempt to open the email, the
apache-
process segfaulted. after some try, i could fetch a strace-log from the
process.
you can found it here: http://dpits.de/segfault.log
thank you!
bye

I upgraded from 4.1.2 to 4.2.3 yesterday and have seen many seg faults
in the error_log when I came in this morning.
I am using Apache 1.3.26, mod_ssl 2.8.10, Openssl 0.9.6g, Compaq Tru64
4.0G.
My PHP configure is pretty basic:
./configure --with-mysql --with-imap --with-curl --quiet
--with-apxs=(path_to_apxs)
We, also, are using IMP (2.2.7). I have not tried to produce the
seg-faults

Reclassified as PCRE related. [2002-09-20 01:42:06] [EMAIL PROTECTED] sorry, i forgot to mention that I tried running the snapshot without zlib support (and png and dom xml support) and got IMP to somewhat work under that environment. However, like I said previously the snapshot did not fix the seg fault problem I am having. Please let me know what you want to do next Thanks [2002-09-20 01:40:23] [EMAIL PROTECTED] unfortunately, this does not fix the original problem, I still get seg faults when viewing messages (no particular message). I'll try to post a backtrace a little later [2002-09-20 01:22:45] [EMAIL PROTECTED] Ok, did this with the new snapshot, however I've figured out what causes the PHP 4.3.0-dev to hang. Basically if I use the --with-zlib configure option, a simple fails to load correctly. If I take this option out, then the displays correctly. I then tried to reinstall zlib (in case it was somehow messed up in RedHat) but that made no difference. I tried different variations of --with-zlib such as: * --with-zlib * --with-zlib=/usr/local * --with-zlib=/usr * --with-zlib=/usr/local --with-zlib-dir=/usr/local * --with-zlib=/usr --with-zlib-dir=/usr If I use any of these, PHP scripts fail to load with the new dev snapshot. However, I am using this option with 4.2.3 with no problems. Maybe its a bug in the dev snapshot? If you need any more information let me know.
