Prior to the following commit, IPv6 worked fine: http://docs.freebsd.org/cgi/getmsg.cgi?fetch=3707253+0+/usr/local/www/db/text/2013/svn-ports-all/20130623.svn-ports-all Now if I try to access a site with mod_rpaf2 enabled, the httpd process segfaults. Unfortunately I'm not able to get a decent stacktrace. Removing the patch and recompiling the port resolves the issue. #0 0x0000000804858fa8 in .rodata () from /usr/local/libexec/apache22/mod_rpaf2.so [New Thread 802807400 (LWP 100191/httpd)] (gdb) bt #0 0x0000000804858fa8 in .rodata () from /usr/local/libexec/apache22/mod_rpaf2.so #1 0x00000008006638a7 in dlinfo () from /libexec/ld-elf.so.1 #2 0x0000000800663a18 in dlclose () from /libexec/ld-elf.so.1 #3 0x0000000801939e84 in dso_cleanup (thedso=Variable "thedso" is not available. ) at dso/unix/dso.c:72 #4 0x000000080193ee5d in run_cleanups (cref=0x802823048) at memory/unix/apr_pools.c:2352 #5 0x000000080193fabe in apr_pool_clear (pool=0x802823028) at memory/unix/apr_pools.c:772 #6 0x000000000042421d in main (argc=1, argv=0x7fffffffdd38) at main.c:696 >How-To-Repeat: Use latest mod_rpaf2 port, have an IPv6 client access the reverse proxy in front of Apache and watch Apache segfault. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
