>Description:
www/firefox has alignment issues on 64-bit architectures like UltraSparc. It builds fine from pkgsrc, but when it comes to installing and registering components it fails with 'Bus error'

Other programs based on Mozilla are likeley to have the same problems and should incorporate the patch given below.
>How-To-Repeat:

>Fix:
Apply the following patch to fix the alignment issues:
