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.
