// gcc bug squishers,
//   The following short C++ file causes gcc to crash.  I've played
// around with this file a bit, and it seems to me that the combination
// of the extern declaration and the virtual function is the culprit.
// (But, then again, what do I know?)
//
// I'm running SunOS 4.1.2 on a Sparc IPC.
// The version of gcc is 2.2.2.
//
// Good luck and thanks for the compiler!
