# apachectl startssl
Segmentation Fault
/opt/apache/sbin/apachectl startssl: httpd could not be started

Environment and configure line....
CFLAGS=-O2
EXTRA_LIBS="-lc-client -lmcal -lsocket"
unset LD_LIBRARY_PATH
export CFLAGS EXTRA_LIBS
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --with-apxs=/opt/apache/sbin/apxs --enable-track-vars --enable-calendar --with-gdbm --enable-filepro --enable-dbase --enable-ftp --with-imap --with-java=/usr/java1.1 --with-ldap=/usr/src/openldap-1.2.9 --with-ibm-db2=/opt/IBMdb2/V7.1 --enable-trans-sid --with-mysql --enable-sysvshm --enable-sysvsem --with-mcal=/usr --with-ming --with-openssl --with-gd --with-pdflib --with-jpeg-dir=/opt/sfw --with-png-dir=/opt/sfw --with-zlib

Library versions:
gdbm 2.x
c-client (imap) 4.7b
java 1.1.8
openldap 1.2.9
IBM db2 7.1
mcal 0.6
mcaldrivers 0.8
ming 0.1.1
openssl 0.95
gd 2.0.1
pdf 4.0.0
jpeg 6.x
png 2.x
zlib 1.x
PHP 406 build successfully on the same machine with the same configure line, and the same environment except I add -lldap -llber to EXTRA_LIBS for 4.0.6, I took those out on 4.1.1 because it caused duplicate symbols to be defined, and php would not compile. After I took those out, php 4.1.1 compiled, but it caused a segmentation fault when I tried to start the web server. PHP 4.0.6 works fine.


Any ideas?

Please read instruction before you submit bug report :)
If httpd segfaults, attach backtrace.

Sorry about the double post, had some problems with this web site. Here's a backtrace with at least some symbols.....

 Interesting, I removed the ldap support, and I nolonger get a segmentation fault, apache httpd just exits....

??????
 [2002-01-24 11:48 UTC] doc at vulcanmicro dot com 
Oh yes...

Server version: Apache/1.3.19 (Unix)
 [2002-01-24 11:49 UTC] doc at vulcanmicro dot com 
Oh yes...

Server version: Apache/1.3.19 (Unix)
 [2002-01-24 14:13 UTC] doc at vulcanmicro dot com 
Confirmed the same problems in 4.1.0.
4.0.6 and earlier work fine.

You broke it....
:-(

I don't confirm this, but I guess it's a LDAP problem. 

To reporter: Could you add "--enable-debug" option when you configure PHP and produce backtrace again?
 [2002-01-25 02:36 UTC] derick@php.net 
Try to build a static (non-DSO) module too, this makes backtraces a lot more useful.

I have not had time to recompile PHP as requested. I've had "WORK" to do and have been using php 4.0.6 in the mean time, which works fine.
 [2002-02-26 09:29 UTC] doc at vulcanmicro dot com 
PS: I don't know if this should be LDAP related. Without LDAP, 
I don't get a segmentation fault, but apache still doesn't run 
with php loaded, it just exits with NO error.
 [2002-06-29 20:06 UTC] sniper@php.net 
This snapshot should work fine for you:

http://snaps.php.net/php4-latest.tar.gz

Also, make sure your apache is linked with libpthread.
This page has some info on how to do that: http://www.php.net/manual/en/ref.oci8.php (yes, it's for oracle. But the procedure is the same anyway)

Reopen this bug report if you get the same problem with that
snapshot. Or with any release >= 4.2.1
