    Example to reproduce the bug (using Python trunk):
    ---

    from gc import collect
import _lsprof

def callMethod(obj):
    obj.clear()
    collect()

obj = _lsprof.Profiler()
obj.enable()
callMethod(obj)
obj.enable()

    del obj
    collect()
    ---

    The problem is that the profiler is still running when exiting
    callMethod() and so it tries to use callMethod context which was
    free'd just before by profiler_clear().

    I'm unable to reproduce my issue with Python trunk, so close it.
