Bug #11716 Updated: Segmentation fault(coredump) in Apache(DSO-enabled) startup

ID: 11716 Comment by: vervoom@hotmail.com Old Reported By: cmlee@users.sourceforge.net Reported By: vervoom@hotmail.com Status: Open Bug Type: Apache related Operating System: AIX 4.3.3 PHP Version: 4.1.1 New Comment: Sorry about last comment, I was a bit stressed out earlier! My environment is: AIX 4.3.3.0 PHP 4.1.1 Apache 1.3.22 VAC.C 5.0.0.2 (IBM Visual Age C Compiler) I think there's a definite problem with your make install script though with regards to extracting the libphp4.so to /apache/libexec. I got round that with ar -x libphp4.a and then running make install again. Also there's something wrong when I dynamically load the library because it's causing a coredump. It's really frustrating. I remember having exactly the same problem on Solaris a few months ago, but I've forgotten what I did to fix it (even more frustrating!). I thought it was something to do with a linker PATH variable? Do I need to set some variable to point at /usr/local/include/php? Should I change something in the php.ini file? I really don't want to change compilers at this stage because everything else is working fine with VAC. Does this have anything to do with the compiler fix mentioned in BUG 4630? I'll try that tomorrow. OK Well that's all I can think of. My configure was pretty basic: ./configure --with-apxs=/opt/apache/bin/apxs --without-mysql Are there some other options I should have added? Cheers, JS. Previous Comments: ------------------------------------------------------------------------ [2002-01-29 06:37:18] vervoom@hotmail.com I'm having exactly the same problem as this: # ./apachectl start ./apachectl[71]: 13068 Segmentation fault(coredump) ./apachectl start: httpd could not be started If I remove the LoadModule libexec/libphp4.so line from the conf, httpd starts OK. I've been looking at the previous reports on this bug, and your answer is always try the latest snapshot. Well considering this problem has been going on for over 2 years now, perhaps we could have a more original answer please?! I've tried 4.0.6, and 4.1.1 and your latest snapshot!! With php-4.1.1 I even had to tinker with your make install script to get it to install properly. If you can't even set this product up to work properly from the start, then that doesn't say very much for it!! Why don't your developers sort it out once and for all, and stop wasting everyone's time (including yours!!)? ------------------------------------------------------------------------ [2002-01-16 05:12:00] cmlee@users.sourceforge.net This is output from make. ############ SKIP ############ mkdir .libs rm -fr .libs/libregex.la .libs/libregex.* .libs/libregex.* ar cru .libs/libregex.al regcomp.lo regexec.lo regerror.lo regfree.lo ranlib .libs/libregex.al creating libregex.la (cd .libs && rm -f libregex.la && ln -s ../libregex.la libregex.la) make[2]: Leaving directory `/home/cmlee/Project/php-4.1.1/regex' make[1]: Leaving directory `/home/cmlee/Project/php-4.1.1/regex' Making all in . make[1]: Entering directory `/home/cmlee/Project/php-4.1.1' /bin/sh /home/cmlee/Project/php-4.1.1/libtool --mode=compile gcc -I. -I/home/cmlee/Project/php-4.1.1/ -I/home/cmlee/Project/php-4.1.1/main -I/home/cmlee/Project/php-4.1.1 -I/usr/local/apache/include -I/home/cmlee/Project/php-4.1.1/Zend -I/home/cmlee/Project/php-4.1.1/ext/xml/expat -DAIX=43 -DUSE_PTHREAD_SERIALIZED_ACCEPT -DAIX_BIND_PROCESSOR -DUSE_HSREGEX -DUSE_EXPAT -I/home/cmlee/Project/php-4.1.1/TSRM -O2 -g -Wall -prefer-pic -c stub.c gcc -I. -I/home/cmlee/Project/php-4.1.1/ -I/home/cmlee/Project/php-4.1.1/main -I/home/cmlee/Project/php-4.1.1 -I/usr/local/apache/include -I/home/cmlee/Project/php-4.1.1/Zend -I/home/cmlee/Project/php-4.1.1/ext/xml/expat -DAIX=43 -DUSE_PTHREAD_SERIALIZED_ACCEPT -DAIX_BIND_PROCESSOR -DUSE_HSREGEX -DUSE_EXPAT -I/home/cmlee/Project/php-4.1.1/TSRM -O2 -g -Wall -c stub.c -DPIC -o stub.lo /bin/sh /home/cmlee/Project/php-4.1.1/libtool --mode=link gcc -I. -I/home/cmlee/Project/php-4.1.1/ -I/home/cmlee/Project/php-4.1.1/main -I/home/cmlee/Project/php-4.1.1 -I/usr/local/apache/include -I/home/cmlee/Project/php-4.1.1/Zend -I/home/cmlee/Project/php-4.1.1/ext/xml/expat -DAIX=43 -DUSE_PTHREAD_SERIALIZED_ACCEPT -DAIX_BIND_PROCESSOR -DUSE_HSREGEX -DUSE_EXPAT -I/home/cmlee/Project/php-4.1.1/TSRM -O2 -g -Wall -prefer-pic -o libphp4.la -rpath /home/cmlee/Project/php-4.1.1/libs -Wl,-bI:/usr/local/apache/libexec/httpd.exp -avoid-version stub.lo Zend/libZend.la sapi/apache/libsapi.la main/libmain.la regex/libregex.la ext/pcre/libpcre.la ext/posix/libposix.la ext/session/libsession.la ext/standard/libstandard.la ext/xml/libxml.la TSRM/libtsrm.la -ldl -lcrypt -lbind -lm -ldl -lcrypt mkdir .libs rm -fr .libs/libphp4.la .libs/libphp4.* .libs/libphp4.* (cd . && ln -s stub.lo stub.o) generating symbol list for `libphp4.la' /usr/bin/nm -B stub.o Zend/.libs/libZend.al sapi/apache/.libs/libsapi.al main/.libs/libmain.al regex/.libs/libregex.al ext/pcre/.libs/libpcre.al ext/posix/.libs/libposix.al ext/session/.libs/libsession.al ext/standard/.libs/libstandard.al ext/xml/.libs/libxml.al TSRM/.libs/libtsrm.al | sed -n -e 's/^.*[ ]\([BCDT][BCDT]*\)[ ][ ]*\(\)\([_A-Za-z][_A-Za-z0-9]*\)$/\1 \2\3 \3/p' | sed 's/.* //' | sort | uniq > .libs/libphp4.exp nm: ext/standard/.libs/libstandard.al[image.lo]: 0654-206 Cannot process the symbol table. ############ SKIP ############ (cd .libs/libphp4.lax/libtsrm.al && ar x /home/cmlee/Project/php-4.1.1/TSRM/.libs/libtsrm.al) gcc -shared -o .libs/libphp4.so.0 stub.o .libs/libphp4.lax/libZend.al/zend_language_parser.lo (.....
