Personally, I would leave the signature as is and cast away the
constness when you eventually add this lazy demangling. My
justification is that the operation is logically a const operation;
you're planning to generate some information on the fly, but it
wouldn't actually change the state of the object.
Obviously this would work better if GDB were written in C++ (since,
for example, we could declare the affect field in the symbol to be
mutable); I'm honestly not sure if my suggestion is idiomatic C or
not. (Then again, const and C have never been the closest of cousins
to begin with.)
