Finally got that debugger attached.  The unexpected exceptions are
std::out_of_range, I think, from bad invocations of
std::string::compare.  The backtraces all resemble

__cxa_throw () from /usr/lib/x86_64-linux-gnu/libstdc++.so.6
std::__throw_out_of_range(char const*) () from
/usr/lib/x86_64-linux-gnu/libstdc++.so.6
std::string::compare(unsigned long, unsigned long, std::string const&,
unsigned long, unsigned long) const () from
/usr/lib/x86_64-linux-gnu/libstdc++.so.6
