Dear clojure-users,
StackOverflowError clojure.lang.RT.nthFrom (RT.java:789)
I got this error message during evaluation of count function call on a
quite short list (about 200 elements). What can be reasons of the error.
Any hints would be greatly appreciated.
Sincerely,

I cannot reproduce your result:
user= (- 500 range doall count)
500
user= (- 500 range count)
500
Could you provide more details? How exactly are you calling 'count' ?

Hi Jim,

so your problem does not lie with 'count' but with something
else...actually 'count' doesn't hold on to the
I tryed to add a call (clojure.stacktrace/e) to the code after the call to
count like this:
...
(if TRACE (println [:ЩАС]))
(if TRACE (do (println [:OFACTS (count ofacts)])

And what a result I have got:

Yes, I fear that you are right. I had a hack through the code last night.
It looks to me like the metadata is set in the
Compiler.load(Reader,String,String) method. This is called from only a
couple of places. From within Compiler, it's called from loadFile.

Or, may be this is not an exception?
use (clojure.stacktrace/e) after the exception has been thrown to get
some more information than just a line. Don't put it in your code,
In this line:
(if TRACE (do (println [:OFACTS (count ofacts)])
(clojure.stacktrace/e)))
the StackOverflowError must be occurring in the evaluation of ofacts.
The error breaks out of the evaluation, preventing
(clojure.stacktrace/e) from being evaluated. The error sends you back to

As far as I can see, though ritz is not Emacs specific per se. It's
a set of middleware for nrepl. So you should be able to build clients
against it for different environments, including a textual one. There's
no reason that a debugger shouldn't be part of lein. I think making it
work with java
Thank you, all, for the very useful information.
Stacktrace after StackOverflowError turns out:

ok we are getting somewhere...is it easy to post the source of your

Solution have found:
(remove ...) = (doall (remove ...))
Full source of 'retract-fact' function is:
(defn retract-fact [fid]
Retract fact for given fact-id by removing it from alpha, beta and fact
memory,
and also by removing from conflict set activations, containing this
fact-id
Did I see a def inside a defn? This is weird... glad you solved your
problem though...

Be careful with this technique. It can easily make your O(n)
algorithm O(n^2). It may be better to use data structures that you
can use with conj and disj if you need to
Jim, please, recommend a correct solution for global variable assignment.
John, Indeed I would prefere technique with better performance. But, as I
understand from scarce documentation, disj works with sets. And doesn't it
recursive?

You don't generally do global variable assignment in Clojure...it is
seriously frowned upon and goes against the functional paradigm... I need
to run now and I will be busy for the next 2 hours... perhaps someone else
can explain if you are in a hurry?
