[webkit-help] why the javascriptcore crashed when enable jit in the webkit version 95542 on android paltfrom?

Wed Feb 8 19:45:25 PST 2012

hi all:
      In my version----webkit 95542, when I set ENABLE_JIT = 1 in android platform, it crashed randomly in android phone. I compile the webkit with arm toolchains gcc/g++ 4.4.0, and the compile mode is LOCAL_ARM_MODE:=arm.
     I think the crash in the jit, because when I set ENABLE_JIT = 0, it will be ok. maybe something wrong with the arm mode generate the binary code, anyone knows how to solve the problem or how to debug it?
