In most situations tests passed just causing a bailout from the compiler due to stack overflow. On Mac some tests actually did crash and of cause some benchmarks showed regressions due to this.

On ARM the break at break slots wrongly used the break at return stub which assumes an object opinter in r0. At break slots there are no objects live in registers so a GC while at a break on a break stub could cause a crash as r0 was wrongly pushed on a internal frame to be handled by GC.
