Yes, this does indeed look like the root cause. With the following

Linaro GCC shows this same problem not just on ARM, but also on i386.
So it seems this may now cause problem elsewhere as well ...

Hmm ... actually there *is* code in the Mozilla sources to attempt to

Ok, so the immediate cause of the bug is that a global array is only
4-byte aligned, but the code silently assumes 8-byte alignment.
The problem triggers in jsatom.cpp:js_AtomizeString:
return (JSAtom *) STRING_TO_JSVAL(JSString::unitString(c));

Confirmed the build failure and segfault in firefox-3.6.8+build1+nobinonly with

Checkout firefox code from mozilla.org, configured, and built. Still segfaults.
Here is a list of steps I did,
1. hg clone http://hg.mozilla.org/releases/mozilla-1.9.2/ 192src
2. cd 192src/js/src
3. ~/autoconf-2.13-install/bin/autoconf
4. ./configure
5. make
./dist/bin/js imacro_asm.js ./imacros.
Runs OK using gcc 4.4.4-6ubuntu2 (i.e. not the Linaro GCC) and
./configure --disable-debug --enable-optimize

I tried cross-building with -marm (this was a bit fragile) but it didn't
help the segfault.

I used Marcin's cross packages, and confirm that --enable-debug in the
above recipe makes the segfault go away.
