My J IDE is broken. Whenever I try to open a new IJS window now, through
File>New or File>Recent or CTRL+N or whatever, this error is raised:
|domain error: wd
| wd'psel ',>i
and no script window appears. Debugging a bit, the fundamental problem appears
to be that the window handles returned by wd'qpx' are negative. For example:
1 {:: , wdforms ''
-1054277158
(this looks like integer overflow to me.) This started happening yesterday,
and is intermittent. By intermittent, I mean that if I get this problem and
close the J session and start another, the problem my disappear, but probably
won't.
I did not change my J installation in any way. The problem started when J
crashed on me yesterday. I think the crash was related to these big files I'm
processing; J seems significantly less stable with a lot of data in memory.
After closing & restarting J a zillion times yesterday, the problem seemed gone
for good. It did not recur for the remainder of the day, or this morning when
I started work.
But now I just had another crash [1]. And it's back. I can't work. Can anyone
help?

[1] I don't know the specific bug that caused the crash, but the sequence of
events was:
* Load my application script, which sets debug mode
and pulls in large file.
* Application then starts processing the file, resulting
in many large nouns in memory (some mapped).
* Application hit an assertion and suspended.
* I typed load'somescript' in the session,
* J crashed (disappeared without error or warning).
This is not the same sequence that caused the crash yesterday.
In fact, I've had many crashes recently, all triggered by different sequences.
Because the situation is so complex, I am not inclined to hunt down the bug(s).
But one thing all the crashes had in common was the large amount of data in
memory.
