GCC has this attribute called abi_tag that they put on any

The usual workaround is compiling the C++ source with
_GLIBCXX_USE_CXX11_ABI=0 for gcc >= 5.
Thats what they said, the GNU guys have a very elegant way of
deceiving people, especially when it comes to backwards
compatibility. they made the flag on by default, and they said
you could just opt out if you want. The problem is, if you opt
out, you can't link to any code out there. because the flag is on
by default and people just don't bother turning it off.
In my case the function is in a cpp library that i don't own, and
wouldn't bother recompiling every library i need to interface to.
If I compile! my code with the flag off, I cannot call any
function that takes std::string or std::list as an argument on
those libraries that were compiled with the flag on. because they
also add a namespace called __cxx11 to std::string and std::list
arguments in the name mangling. and if I compile with the flag
off the namespace disappears.
