Need help figuring out why Javascript "call stack size exceeded"

[Glenn Iba]

Greetings, 

  I'm a total newbie to this group. Hoping to get some help ...

I'm writing a Clojurescript/Reagent app, which among other things, does

some medium size searches to solve puzzles I randomly generate.

My larger searches (some only depth 10 or so) are causing Javascript to

hit its "stack size limit" :

   core.cljs:3816 Uncaught RangeError: Maximum call stack size exceeded

I am using loop and recur instead of pure recursion, so I don't think that's

the issue.

I am using some moderately large hashmaps to store "positions visited by search",

but these should have less than 100k key-value pairs.

Could something to do with these hashmaps be causing the stack issue??

I'm using CONJ to add new key-values to hashmap.

I can't find the call stack to examine what's going on -- is there some way anyone

can suggest for me to do that?  The normal Chrome inspector gives me an uncaught

exception, but I can't seem to access the actual call stack.

Please help - any and all suggestions much appreciated!!

If some kind and generous soul would be willing to look at my code,

I'd be quite happy to share it :)

Thanks in advance!!
