Is this something the JS team can investigate?

Comment 2

I'm unable to reproduce this on my Galaxy S5, can you still reproduce this with recent Nightlies?

I looked at the crash dump, we're crashing at 72edb000. It looks like Baseline IC code, the first 2 instructions make sense but after that it's bogus. Maybe memory corruption somewhere? I can't say much more. Maybe you can try a debug build?
