GDB 5.1.0.1 and GCC 3.0.4 derived classes

[Smith, Jonathan C5]

I've noticed a bizarre error when using GDB 5.1.0.1 with a C++ binary
compiled using GCC 3.0.4.  When attempting to display objects, I found two
of our derived classes could not be printed.  The error was, "Value cannot
be converted to an integer."  These include virtual pointers and they are
printed out when the binary is compiled under GCC 2.94.

Is this a known issue?  If so, when will a fix be available?

Thanks,

Jonathan Smith
