--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The gdb backtrace shows your program is linked to the wrong libstdc++.so that
comes from the gcc-4.4.7 system compiler, not the one from gcc-7.2.1 that you
compiled with.

See
https://gcc.gnu.org/onlinedocs/libstdc++/faq.html#faq.how_to_set_paths
and
