I don't know how to file bug so I posted here.
In privateCompileCTIMachineTrampolines() there are multiple align() to align 
code on 16byte margin, yet, the stack can be put on 32bit margin that causes 
crush.
Suppose original stack is aligned to 8/16bytes, the above function frequently 
pop/push regT3 that makes stack mis-aligned. Then int to double conversion uses 
stack that will fail.
