panic called by the program

panic · spec 06-errors

The program called panic(message), or a function of the standard library did on a broken precondition (a negative capacity, a radix outside 2 to 36, a format string with a brace left open). The message is printed as written, with the backtrace; the process exits with 101, or a task ends with the panic as its status.
