While this doesn't help *you*, it should help the current C++ people 
for GDB:
I've seen this with STABS debugging info when some of the operator 
functions were left out of the debugging info, but others weren't (GCC 
+ STABS will omit unused functions from debug info), and we ommitted 
the operator we really need to use, and in some cases when we parsed 
the types of the arguments out of the demangled function name and come 
up with some weird type.
