Yes, this bug is worth fixing.
But it's much less serious than many others: x E. y numeric, or x f@:e.
y, ,&.>/ y, etc.; see
http://code.jsoftware.com/wiki/System/Interpreter/Bugs/Errors
and
http://code.jsoftware.com/wiki/System/Interpreter/Bugs/Crashes
We don't need a fix for this bug: we need a process for fixing bugs.
And then we need a process for moving the language into a multi-core and
GPU world.

I think this bug is serious. If anyone can provide a patch
based on the j701 GPL source and related test script,
then I can merge the fix into the next release.

The chance of getting that with no bug is about 1 in 10^86. There's a bug.
The question is, Why can't we just fix it? If I wanted to put in the
change, how would I do so and get the change into a release?
We have a bug list of 50 or so errors, some serious. If this language is
going to live, it needs to be able to grow.

I think there are already enough evidences to call for
further investigation to prove or disprove the bug.

one less leading 2 in first example. 47 leading 2s, correct result. 48
leading 2s and everything is 2.
So?
Consider this:
?.4#4
2 0 0 2
4{.?.400#4
2 0 2 0
The size of the right argument influences the values generated at each position.
You would need to perform a large number of experiments to show a
statistical flaw in the results.
