Segmentation Fault on new soapclient() function call in php.

umangjain · February 4, 2011

Hi guys,

I am having trouble in using SOAP extension. I installed PHP with SOAP extension but whenever there is a soapclient function call in the code.

The page either doesn't load and shows a blank page or asks to save the .php file without even showing a blank page.

In error log file for apache this error is thrown again and again on each page load:

[Thu Feb 03 23:02:20 2011] [notice] child pid 23912 exit signal Segmentation fault (11)

I tried backtracing it using gdb. But it came out with this which makes no sense:

[root@testapp3 bin]# gdb /usr/sbin/httpd /tmp/apache-cores/core.8638

GNU gdb Red Hat Linux (6.5-16.el5rh)

Program terminated with signal 11, Segmentation fault.

I used the same php code on other machines and it works fine. Please put some light on the problem here.

Please help.

Thanks,

Thanks for trying guys. I got it fixed eventually.

Just to tell others if anyone else gets this problem:

I installed openssl, zlib and libxml iin the system.

Changed symbolic links in /usr/lib directory for libz (to do this check this page: http://openhelp.net/2010/11/11/libxml2-so-undefined-reference-to-gzopen64/ )

And then everything worked. I didnt even had to reinstall apache or php.

Thanks,

Umang
