           Summary: Segmentation Fault
           Product: Apache httpd-2
           Version: 2.2.14
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: critical
          Priority: P2
         Component: All
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: aurabhi@yahoo.com


I have a apache 2.2.14 running Solaris 5.10
Apache is built using SunStudio 12 Update 1. 
On this setup I have a custom module and wlproxy(mod_wl_22.so)
When I request pages which are delivered via wlproxy(mod_wl_22.so) I see
segmentation faults. The requests are server properly but at the end of every
request I see the following error

[Wed Dec 23 21:08:52 2009] [notice] child pid 11624 exit signal Segmentation
fault (11)

Following is what I see when I opened the core in dbx 

bash-3.00# dbx httpd /tmp/apache2-gdb-dump/core
For information about new features see `help changes'
To remove this message, put `dbxenv suppress_startup_message 7.7' in your
.dbxrc
