My Mercury program compiles just fine but if I try to run it I get an error without its accompanying stack trace
What do you understand or find about that problem
I’m trying to finish a challenge that involves a lot of list operations, however when I run the program it tells me that there’s an Index out of bounds somewhere, the thing is, the only information I get, the guilty method, is one I don’t even use once throughout my code.
You make any workaround? What did you do?
I have tried to switch off parts of the code and check the output, but there are too many ways this could be done, I looked at the list boundary checks and they all seem sound to me. I’ve also tried to find out how to install a different ‘grade’ to allow debugging or at least see the stack dump but to no avail.
I have to mention again that I haven’t used this method once throughout the code, I did use its sister method det_index1 which is a 1-based list getter.
I need help with
Installing a mercury grade that allows me to see where this error is coming from.
