I tried to generate backtrack on ARMv7, but unfortunately gdb crashes
on debug build of JSC. :(
But it seems the bug is in the DFG JIT somewhere, because
stress/op_sub.js passes with disable DFG, but crashes by default.
I had a release backtrace. I don't think if it helps, but who knows.

Backtrace stopped: previous frame identical to this frame (corrupt stack?)
I'll try to create a debug backtrace on AArch64, but I will
have time for it only tomorrow morning (in CET timezone).</pre>
