Fatal error

Sounds like the input line was padded with "blank space" characters (when first displayed) instead of "null" characters. There's a difference.

Usually if the input is padded with blanks, no issues. Null characters might be, but there are more than just blanks and null characters that might not be visible so blanking them out blindly worked even having the fact that there's somewhere in the input stream one or few invisible ones are "hiding".

I don't know what language is being used. Could be a initialization issue, boundry issue, etc.

Whew.  What a relief.

From the title "fatal error" thought you had sold off your wife's Lexus convertible and bought yourself a pair of 150 pound monoblocks.
