[elephant-devel] Memory corruption in open-store

[Andrew Kirkpatrick]

Hi, I'm trying to use elephant but with limited success. Running on 
Ubuntu 9.04, with clbuild installed SBCL 1.0.35.1 and current Elephant 
and dependencies. I tried using contrib/henrik/install-bdb.sh to install 
Berkeley DB 4.5 and set up my-config.sexp as it suggested, but when I 
evaluate this form, referring to a directory that does exist:

(open-store '(:BDB "/tmp/my-db/"))

I get a the usual compilation and loading noise terminated with:

Help! 11 nested errors. SB-KERNEL:*MAXIMUM-ERROR-DEPTH* exceeded.
0: ; Evaluation aborted.

I've also tried configuring my-config.sexp to use libdb-4.6.so and 
related files installed from the Ubuntu repo, but the effect is the 
same. In both cases its loading the correct shared lib, and when I 
switch to the *inferior-lisp* buffer, the 11 nested errors all look 
similar to this:

CORRUPTION WARNING in SBCL pid 3239(tid 3039865744):
Memory fault at 100020 (pc=0x9c77963, sp=0xb52f6110)
The integrity of this image is possibly compromised.
Continuing with fingers crossed.

Indeed at that point my lisp image is somewhat hosed. I started trying 
to use the :BDB store because of similar errors when the cl-sql backend 
tried to use sqlite.

I realize this it probably CFFI related, but perhaps others have run 
into it and know of a fix?

Thanks,
