Loaded symbols for /usr/libexec/ld.elf_so
#0  0x00007f7ffc028e98 in XFindOnExtensionList ()
   from /usr/pkg/xorg/lib/libX11.so.6
(gdb) quit

Programs that use libX11.so crash with signal 10 and leave a core.

This happens only on amd64 port. On i386 they work fine.


>How-To-Repeat:
Compile xorg-libs,xorg-server,xorg-clients and then run a program
e.g xterm.
>Fix:
Mihai CHELARU suggested compiling xorg-libs with the use of
"-fno-strict-aliasing" flag which corrects the problem.
