50 | * Inserts a breakpoint instruction into the code. |

52 | * On architectures which support it, this is implemented as a soft interrupt |

54 | * |
55 | * `SIGTRAP` is used rather than abort() to allow breakpoints to be skipped past |
56 | * in a debugger if they are not the desired target of debugging. |
