Did you have this problem in 1.4?  We use Elephant extensively on Clozure on Mac/Linux under 1.4 but I haven't upgraded to the latest 1.5 on any system that I'm aware of.  There are some occasional bugs found in the schema management code too that may be lurking.

hi eslick:
This problem will also occure in 1.4,but not so often.

If i try my operation one or two times,the operation will work fine again.

Greetings

I've run into a problem on the latest Elephant 1.0 from the darcs
repository, with SBCL 1.0.34 on FreeBSD and 1.0.39 on MacOS.
(make-pset) fails with a deserialization error (steps below).  Other
operations like creating and initializing a persistent class, or
adding to the root, work fine.  Am I doing something silly?
