You can turn off the JIT by setting the QV4_FORCE_INTERPRETER=1 environment variable at runtime.

Nothing except a JIT uses pages simuntaneously writeable and executable -- they're a major security nightmare. Unfortunately, I need to know what called it. That's why you need to use 5.2.0 and a debug build. You might need to turn JIT off in V4 too. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
