The C++ program below illustrate a g++ bug. The function getx() is called
twice, once when x.f() is invoked. When compiled under Zortek C++ getx() is
called only once, as I would expect.
Please let me know if this is a known problem, to be fixed, etc. Thanks!

* Looks like getx() is being called again when x.f() is executed.
