--- Comment #3 from Pedro Alves <pedro at palves dot net> ---
Sounds like it, yes.  Thanks tracking that down.

I'm not sure off hand what is the best fix.  

I mean, it's probably something around skipping the test for gcc < 8 (C++11 ABI
support was added around GCC 5 IIRC, but older ones should just test the same
thing twice so pointless to let them run the _GLIBCXX_USE_CXX11_ABI=1 tests) or
something.

Or maybe the testcase .cc file could define std::string typedef itself on such
compilers.  

We could test std::__cxx11::string too, though that wouldn't exercise the
original issue the testcase ran into, with the special mangling feature for
"std::string", so seems a bit pointless too.

Or something else.

In any case, it doesn't look like a GDB bug.
