Note multiple copies of the libstdc++ will not fix the issue here since
libtcmalloc provides a free which does not work with aligned_alloc. In fact it
would just fall over the same way. As I mentioned

_Float128 is supported in older c++ standards for gcc. That is it does not
error out for -std=gnu++11 even.

My problem is that I need from_chars/to_chars for __float128 also for older C++

--- Comment #3 from Nicholas Miell ---
Windows and macOS (and Solaris) have sensible dynamic linker semantics where
the pre-C++17 code and the post-C++17 code uses two different C++ runtimes and
furthermore the application can use tcmalloc
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113258
--- Comment #2 from Andrew Pinski ---
So the situtation here is you have a pre-C++17 application using a C++17
library.
If the application was C++17 and using a C++11 library, it would just work.
So the ABI is broken in the C++17 library

--- Comment #1 from Andrew Pinski ---
This is a C++ standard issue I suspect which cannot be fixed just in libstdc++.
I suspect libc++ and MSVC's C++ library all have a similar issue too.
