Comment #7 on issue 2389 by [email protected]: PeaceKeeper Benchmark not running with latest v8..
http://code.google.com/p/v8/issues/detail?id=2389

Finally seems to be the root cause is found.
With 3.13.7.0 v8 version the peacekeeper site works(but later versions does not work)
Changes made are:-->
1)es5_readonly flag to false(flag-definitions.h)
DEFINE_bool(es5_readonly, false,
            "activate correct semantics for inheriting readonliness")
2)In EmitDeepCopy function removed static casting(lithium-codegen-arm.cc)
// We only support little endian mode...
        int32_t value_low = value & 0xFFFFFFFF;
        int32_t value_high = value >> 32;

Can any one let me know why these changes are causing this Issue
