[elephant-devel] (get-from-root "key") results in "Heap exhausted" error

[Joubert Nel]

Hi,

I've just started using Elephant and have run into a "Heap exhausted" error 
message when I try to retrieve a key's value from the root. I am doing:

	(add-to-root "first" "joubert")
	(get-from-root "first")

After the 2nd expression I get the results as per the attachment.

I'm running with the following config:
	Elephant 0.6.0
	cl-base64 3.3.2
	uffi 1.5.17
	BerkeleyDB 4.3
	SBCL 0.9.17
	SUSE Linux 10.1 AMD64.


Any pointers?

Regards
Joubert
