        src/sys/compat/svr4: svr4_signal.c
Log Message:
If a null pointer argument is passed to setcontext(), exit the process; it
would appear that overloading the argument this way is used by SVR4 to `fall
off' the main context (uc_link being NULL) after a function set up using
makecontext() returns.
