# Default behavior of signals in Go programs

By default, a synchronous signal is converted into a run-time panic. A
SIGHUP, SIGINT, or SIGTERM signal causes the program to exit. A
SIGQUIT, SIGILL, SIGTRAP, SIGABRT, SIGSTKFLT, SIGEMT, or SIGSYS signal
causes the program to exit with a stack dump. A SIGTSTP, SIGTTIN, or
