Thank you, all, for the very useful information. Stacktrace after StackOverflowError turns out:
StackOverflowError clojure.lang.RT.nth (RT.java:764) rete.core=> (clojure.stacktrace/e) java.lang.StackOverflowError: null at clojure.lang.RT.nth (RT.java:764) rete.core$fact_id.invoke (core.clj:403) rete.core$retract_fact$fn__1902.invoke (core.clj:633) clojure.core$complement$fn__4048.invoke (core.clj:1357) clojure.core$filter$fn__4226.invoke (core.clj:2533) clojure.lang.LazySeq.sval (LazySeq.java:42) clojure.lang.LazySeq.seq (LazySeq.java:60) clojure.lang.RT.seq (RT.java:484) nil rete.core=> This list with a problem *ofacts* was been intensively updated by *cons* and *remove* operations (more precisely, *rete.core/retract-fact* function visible in stacktrace contains a call to *remove*). Thus, probably, John is nearer then others to solution. So, the question is: What can I do to avoid recursive *remove* operation? May be I should rewrite it using *loop*? Does this help? Or recursion remains inside *loop*? пятница, 8 ноября 2013 г., 13:17:28 UTC+4 пользователь ru написал: > > 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).
