The goal is to raise the error message with the most bytes! The error message may not be generated by the program itself, such as Python's
raise. errors that do not terminate the program are not allowed unless they do not show an error message.
Here is an example in python that raises 243041 bytes of error code:
def a(m): try:-'' except: if m>0: a(m-1) else:-'' a(900)
