067 Possible mis-compilation with Intel Compiler.

    The following snippet fails against a Coin built with the Intel
    Compiler, at least with versions 5.0 and 7.0:

    --------------8<----------- [snip] ------------------8<--------
    #include <Inventor/SoDB.h>
    #include <Inventor/events/SoMouseButtonEvent.h>

    int
    main(int argc, char ** argv)
    {
      SoDB::init();
      SoMouseButtonEvent::getClassTypeId();
      return 0;
    }
    --------------8<----------- [snip] ------------------8<--------

    The call-stack backtrace is nonsensical.
