Found usecase where reults vary from one run to another
The attached code gives different results in one run and another in my computer. Only merge function is tested. Versions: sortednp 0.2.0 numpy 1.16.2 python 3.6.7
I could not replicate the problem with arrays created directly from lists. It might be caused by the slice but sadly I found my level too low to follow the sortednp source code to narrow down the scope of the issue myself.
