I was using roll to generate some random varchar data in jgtk.
Specifically, the line I executed was
<@(a.{~?&256)"_1 @ ?&256 ]10
I was very surprised to see output that included a run of 302 chars that
is a direct quote from a script I had open (but had not run).
I know some pseudorandom generators do things like read system memory,
but the vocab says J uses the Mersenne Twister algorithm by default,
which I think shouldn't behave like this.
Could this be some weird GTK display glitch? I was simultaneously
experiencing the bug where it can't properly draw boxes.
Has anyone else seen this behavior? Unfortunately it's probably next to
impossible to duplicate.
