The following piece of code does not work on Ubuntu 20.04. load 'primitives'
perm =: i.@! A. i. PanDigS =: (perm 10) from (1 + i.10) PanDigT =: 10 base"1 each 3 box\"1 PanDigS The effect is variable: crash of the J interpreter, freeze of the Qt interface or even of the whole system. It shows up both on J807 and J902. The dataset is quite large: 7!:5 <'PanDigS' 5.36871e8 and the process crashes (or the system freezes) after several seconds. Hence, I suspect an issue with memory management. Any idea or suggestion on how to bypass the problem?
