On Codewars, this error was usually seen when a solution attempted to dereference a past-the-end iterator, usually returned by `end( )` or by some function which signals some negative outcome by returning `end` iterator (for example, `std::find(myvec.begin(), myvec.end(), someValue)` will return `myvec.end()` if value is not found).
There are some common causes for this problem:
- attempt to dereference a past-the-end iterator, usually returned by `end( )` or by some function which signals some negative outcome by returning `end` iterator (for example, `std::find(myvec.begin(), myvec.end(), someValue)` will return `myvec.end()` if value is not found).
- Division by zero (including modulo with zero divisor)

### Exit code 137
