nsID 64-bit alignment issue was already tracked down:
https://bugzilla.mozilla.org/show_bug.cgi?id=660335.

>From what I understand, patch V3 performs struct alignment using GCC
or MSVC-specific keywords. Iceweasel 7.0.1-2 in current Debian
"Wheezy" Testing doesn't seem to include this patch (yet).

I'll apply it locally in order to check if other unaligned accesses
nevertheless surface.
