Fix Issue with Coverage Pipeline due to "TypeError: Cannot interpret 'int64' as a data type"

It appears the pipeline of the after the last merge request (MR !109 (merged)) fails due to TypeError: Cannot interpret 'int64' as a data type. I suspect this is because I mistakenly used INT instead of INT_DTYPE when I initialize arrays in the JIT-compiled function.

Curiously, though, this error was not raised in the testing carried out when a merge request is opened.

I'll attempt a fix for this issue.
