>From what I saw with gdb, the handler address retrieved in ctiVMThrowTrampolineSlowpath function in r1 register is likely to be the address of ctiOpThrowNotCaught, where registers are restored from JIT stack frame.

So without this patch, we did the work twice, leading to unexpected values and misplaced stack pointer during the "second restore from JIT stack frame" in ctiOpThrowNotCaught.
