mod_proxy coredumps in proxy_fixup(), mod_proxy.c:279

           Summary: mod_proxy coredumps in proxy_fixup(), mod_proxy.c:279
           Product: Apache httpd-2.0
           Version: 2.0.48
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: mod_proxy
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: tom@izb.net


I configured httpd-2.0.48 with mod_proxy as intranet proxy server. When
connecting to http://www.mydrive.netapp-web.com/ httpd child coredumps on every
graphic load attempt. Graphics from other sites are working.

I'm using SunOS 5.9 (Solaris9) on an E2/sparc.

gcc -v:
Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.9/3.2.2/specs
Configured with: ../configure --disable-nls --with-ld=/usr/ccs/bin/ld
--with-as=/usr/ccs/bin/as
Thread model: posix
gcc version 3.2.2


httpd configure command:
./configure --enable-mods-shared=all --enable-file-cache=shared
--enable-cache=shared --enable-disk-cache=shared --enable-mem-cache=shared
