/usr/include/c++/5.1.1/debug/functions.h:315: const _CharT*
__gnu_debug::__check_string(const _CharT*) [with _CharT = char]: Assertion '__s
!= 0' failed.
Aborted
I was hitting this issue often on some older GCC versions but now I find it
very difficult to reproduce. __glibcxx_assert() is probably no longer too much
used. For some reason I could no longer even reproduce it with std::string.
