And the OS is windows xp. I had met the same problem in arm platform. I had done the same thing using r67643 code, and found no problems. And I had tried to build r69847 code using the macro #define ENABLE_JIT 1 #define ENABLE_JIT_OPTIMIZE_CALL 0 #define ENABLE_JIT_OPTIMIZE_NATIVE_CALL 0 #define ENABLE_JIT_OPTIMIZE_PROPERTY_ACCESS 0 #define ENABLE_JIT_OPTIMIZE_METHOD_CALLS 0 and nothing problem was found. By a way, the file JITPropertyAccess.cpp's function emit_op_put_by_id, a sentence is like that: JITStubCall stubCall(this, direct ? cti_op_put_by_id_direct_generic, cti_op_put_by_id_generic); should't it be the next sentence? JITStubCall stubCall(this, direct ? cti_op_put_by_id_direct_generic : cti_op_put_by_id_generic); please check, thanks. 295281 7 oliver 2010-10-17 14:24:21 -0700 (In reply to comment #6) > I build
