16.2 Calling a pure virtual function

Calling a pure virtual function is illegal. If your code calls a pure virtual function, then the compiler includes a call to the library function __cxa_pure_virtual.

__cxa_pure_virtual raises the signal SIGPVFN. The default signal handler prints an error message and exits.
