Is this bug 776126?
I think so.
Hmm, maybe not.
I assume you've done the whole clobber/autoreconf dance?
`rm -rf objdir && make -f client.mk` should be enough? The difference between this bug and the other is that I'm not using the same mozconfig options: I'm not using a shared js but I'm using a system zlib.
I confirm, it's because of system-zlib.
Fails for me, too.
Can you attach your build log? I can't reproduce.
I can reproduce this bug during building Thunderbird but not reproduce during XULrunner.
Build environment: Fedora 17 x86_64 gcc-4.7.0 zlib-1.2.5
Ah, I finally reproduced.

For those who would apply the patch: note ccache is not being very helpful in this case. Use CCACHE_RECACHE=1 make -C objdir/js/src jsutil.o
