(gdb) print name()
pure virtual method called
The program being debugged entered a std::terminate call, most likely
caused by an unhandled C++ exception.  GDB blocked this call in order
to prevent the program from being terminated, and has restored the
context to its original state before the call.
To change this behaviour use "set unwind-on-terminating-exception off".
Evaluation of the expression containing the function (__cxa_pure_virtual@plt)
will be abandoned.
