I've also seen this problem with clang-3.4 on i386.  It looks like a
clang bug to me.  Clang is putting ud2 instructions in its output which
are guaranteed to fault when it compiles nsAppRunner.cpp.  See
<http://www.freebsd.org/cgi/query-pr.cgi?pr=187103>.

I tried compiling the offending file with gcc46 and didn't see the
problem in the assembly output.
