Nothing in the ChangeLogs jumped out.

I don't see GCC being motivated to fix it though :-(

Which leads to the question. Why does GDB demangle symbols? My
simplistic understanding of the code is that GDB only needs the "iw"
(a.k.a., demangled string up to but excluding the lparen and ignoring
white space) part of the symbol in the search table (the rest isn't so
critical and can be constructed on-demand).
