I can reliably reproduce the problem. We will take a look at it. The
bug has been with us for a long time and it may be a while before it
is fixed.
The simplest way to see the bug is to load the following script and
then display bb. Changing anything hides the bug.
*** bad.ijs
bb=: 2 ]/\ i. 10
bx=: 2 ] \ i. 10
(":bx) 1!:2[2
***
Thanks for your persistence in reporting this problem.
