Bug description: Crash occurred in function strlen from module /lib/libc.so.1
Description:
------------
Compiled php using nsapi as follows:
1.) Install openssl
NOTE: the "shared" option below is REQUIRED for SASL.
PATH=$PATH:/usr/sfw/bin:/usr/ccs/bin
export PATH
./config --prefix=/usr/local/ssl shared
make
make install
2.) Install BerkeleyDB
cd build_unix
../dist/configure
make
make install
3.) Set Environment now.
LD_LIBRARY_PATH=/usr/local/ssl/lib:/usr/local/BerkeleyDB.4.6/lib:$LD_LIBRARY_PATH
LDFLAGS="-L/usr/local/ssl/lib -R/usr/local/ssl/lib
-L/usr/local/BerkeleyDB.4.6/lib -R/usr/local/BerkeleyDB.4.6/lib"
export LDFLAGS

export CFLAGS
CPPFLAGS=$CFLAGS
export CPPFLAGS
PATH=/usr/local/ssl/bin:/usr/local/BerkeleyDB.4.6/bin:$PATH
export PATH
4.) Install SASL
./configure --prefix=/usr/local/sasl --with-openssl=/usr/local/ssl
make
make install
5.) Update Environment.
LD_LIBRARY_PATH=/usr/local/sasl/lib:/usr/local/ssl/lib:/usr/local/BerkelyDB.4.6/lib:
exoprt LD_LIBRARY_PATH
LDFLAGS="-L/usr/local/sasl/lib -R/usr/local/sasl/lib

PATH=/usr/local/sasl/sbin:/usr/local/ssl/bin:/usr/local/BerkeleyDB.4.6/bin:/usr/sbin:/usr/bin:/usr/sfw/bin:/usr/ccs/bin
export PATH
6.) Install openldap
./configure --prefix=/usr/local/ldap --with-tls --enable-wrappers
--enable-crypt --enable-bdb --disable-slapd --disable-slurpd
make depend
make
make install
7.) Update Environment
LD_LIBRARY_PATH=/usr/local/webserver/lib:/usr/local/ldap/lib:/usr/local/sasl/lib:/usr/local/ssl/lib:/usr/local/BerkelyDB.4.6/lib:
export LD_LIBRARY_PATH

export PATH
8.) Install php
./configure --with-ldap=/usr/local/ldap --with-gettext
--with-openssl=/usr/local/ssl --with-nsapi=/usr/local/webserver

make
make install
Modified the magnus.conf and obj.conf for the web server and instance.
This goes well and I'm able to load a simple phpinfo.php file <?php
phpinfo(); ?> without issue.
We are trying to perform LDAPS connection to MS Active Directory. We have
this code running under Apache on another server. For support reasons we
are trying now to use Sun Java System Web Server 7.0 update 2 (newest) to
achieve the same thing.
Our code runs fine from command line. But when run inside the web server
the following shows in the error log (BTW, yes it is reporting php5 as I've
also tried version 5 as well, both produce the same results).
[21/Mar/2008:12:52:02] catastrophe (15965): CORE3260: Server crash
detected (signal SIGSEGV)
[21/Mar/2008:12:52:02] info (15965): CORE3261: Crash occurred in NSAPI SAF
php5_execute
[21/Mar/2008:12:52:02] info (15965): CORE3262: Crash occurred in function
strlen from module /lib/libc.so.1
I have captured a core file and can send it on (489MB in size) or provide
information from the stack trace.
I am looking for any information of what I may have done wrong or if there
is a bug that I have hit.
Thanks in advance.
Reproduce code:
---------------
The source of php code is very simple.
<?php
# Set server name.
$ldaphost = "ldaps://pittad.univ.pitt.edu";
# Make Connection Handle
$ldapconn = ldap_connect ($ldaphost) or die("Could not connect to
$ldaphost");
# Make sure to use version 3 of LDAP Protocol.
ldap_set_option($ldapconn, LDAP_OPT_PROTOCOL_VERSION, 3) or die ("Could
not set
version 3");
ldap_set_option($ldapconn, LDAP_OPT_DEBUG_LEVEL, 7) or die ("Could not set
ldap
debug level 7");
ldap_set_option($ldapconn, LDAP_OPT_REFERRALS, 0) or die ("Could not set
referrals 0");
# Username and Password
$user='cn=blahuser,ou=Accounts,dc=company,dc=com';
$password='blahpassword';
# filter
$filter='(cn=blahuser)';
print "2<br>\n";
# Authenticate to AD.
$ldapbind=ldap_bind($ldapconn,$user,$password);
if ($ldapbind) {
# LDAP Authentication/Bind Successful.
print "LDAP Authentication/Bind Successful...\n<br>";
#$sr=ldap_search($ldapconn,$base_dn,$filter,$attributes);
$sr=ldap_search($ldapconn,$base_dn,$filter);
$info = ldap_get_entries($ldapconn,$sr);
} else {
print "LDAP Authentication/Bind Unsuccessful.\n<br>";
}
ldap_close($ldapconn);
?>
Expected result:
----------------
LDAP Authentication/Bind Successful...\n<br>
Actual result:
--------------
Web Page hangs and no results in the browser, however error log grows by
the three lines that I have indicated:
