C++ noshowbase ignored

[Michael D. Berger]

In FC7, the line"

...
   cout << "a = 0x" << setfill('0') << hex << noshowbase <<
                     setw(8) << a << dec << setfill(' ') << endl;
...

results in:

a = 0x0x91a1218

Is there something I can do about this?

Thanks,
Mike.

Use an actually supported version of the compiler and runtime.  Later
versions (at least F9) don't have this problem.

Upgrading would be a problem for now.  Is there any
other solution?

Thanks,

Mr. Obvious asked, "how 'bout changing the code like so:"
...
    cout << "a = " << setfill('0') << hex << noshowbase <<
                      setw(8) << a << dec << setfill(' ') << endl;
...

or for more pain

cout << resetiosflags(ios_base::showbase)
????

Mr. Clearly Stated replied, "the code presented is
merely a model to show the problem; the real code
with the problem is much more complex."
