[elephant-devel] STOP-AND-COPY-GC fails

[Leslie P. Polzer]

My first try with the new GC:

MYSTIC(39): (stop-and-copy-gc *store-controller*)
Transaction not specified for a transactional database

debugger invoked on a ELEPHANT-DESERIALIZATION-ERROR in thread #<THREAD "initial thread"
RUNNING {A8C7721}>:
  Elephant deserialization error:
Berkeley DB error #22: Invalid argument

Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL.

restarts (invokable by number or by possibly-abbreviated name):
  0: [ABORT] Exit debugger, returning to top level.
