Bug 107644 – glibc error running apache/php/phpldapadmin

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Vijay Avarachen 2005-09-29 14:36:22 UTC]

I have phpldapadmin installed.  Whenever I try to use it I get very poor
performance.  Most time the page won't even load fully.  I have to hit the
refresh button multiple times to get the page to load all the way.  After a
little digging around I noticed the following error messages in my apache log file:

"*** glibc detected *** corrupted double-linked list: 0x40466a4c ***
[Wed Sep 28 23:30:21 2005] [notice] child pid 31339 exit signal Aborted (6)"

I though it might be due to "hardenedphp" flag, so I re-emerge php without that
flag but no luck.

The only thing I can suspect is the "hardened" flag in glibc.

spduslisldap02 apache2 # emerge -pvD apache php glibc

These are the packages that I would merge, in order:

I setup phpldapadmin (same version) on a CentOS box and it worked flawlessly.

Reproducible: Always
Steps to Reproduce:
1.Start Apache with phpldapadmin installed/configured
2.Use phpldapadmin
3.
Actual Results:  
The page will hang frequently, form buttons won't show up, only partial pages
will load.  User has to refresh page multiple time to get the page load properly

Expected Results:  
Web pages should load quickly
Changes made to ldap should show immediately
All form options should display

I recently emerged the latest Apache (2.0.54-r31), PHP (4.4.0-r3) and
phpLDAPadmin (0.9.7_alpha6) and same results.

for me similar, esp. when PEAR_Error object called, but got some with php's
gettype, seems there's no rule why it comes.
Usu it's 
*** glibc detected *** free(): invalid next size (fast): 0x085d8298 ***
Abort
but coredumps from time to time.

PHP bumped recently for me (4.4.0-r3).

[Comment 4 Kamil Gornik 2005-11-13 15:45:45 UTC]

oups, 4.4.0-r4, my mistake

[Comment 5 SpanKY 2005-12-02 20:30:02 UTC]

most likely bug in apache/php, not in glibc

[Comment 6 Luca Longinotti (RETIRED) 2006-01-04 03:18:25 UTC]

dev-lang/php-4.4.1-r5 is in, maybe this fixed the mentioned issues, please try that and report back.

[Comment 7 Luca Longinotti (RETIRED) 2006-01-04 03:20:18 UTC]

Sorry, I meant dev-lang/php-4.4.1-r3. :)
