<pre>libc++abi fails to demangle the mangled name generated by clang for an
inherited constructor.
Example name where cxa_demangle fails: _ZN5bbbbbCI25aaaaaEi
Source code for generating the mangled name:
class aaaaa {
public:
aaaaa(int);
};
class bbbbb : aaaaa {
using aaaaa::aaaaa;
};
void ccccc() { bbbbb(1); }
Clang version used to generate the name:
clang version 5.0.0 (trunk 303332) (llvm/trunk 303340)
Target: x86_64-unknown-linux-gnu
Thread model: posix

Open question: What should be the output of __cxa_demangle when demangling an
inherited constructor? What do people think about "bbbbb::bbbbb(int)" (hides
that it is an inherited constructor) or "bbbbb::aaaaa(int)" (hides that it is a
constructor) for the above case?</pre>
