[Sbcl-devel] Failed AVER while in Drakma call
|

We saw this error in our application log. This is the first time it
happened, and I have currently no way of reproducing. However, I'm posting
the stack trace here in case it helps anyone:
<ERROR> [06:12:05] potato.core session.lisp (acceptor-log-message
potato-acceptor) -
failed AVER: (< I 2)
This is probably a bug in SBCL itself. (Alternatively, SBCL might have been
corrupted by bad user code, e.g. by an undefined Lisp operation like
(FMAKUNBOUND 'COMPILE), or by stray pointers from alien code or from unsafe
Lisp code; or there might be a bug in the OS or hardware that SBCL is
running
on.) If it seems to be a bug in SBCL itself, the maintainers would like to
know
about it. Bug reports are welcome on the SBCL mailing lists, which you can
find
at <http://sbcl.sourceforge.net/>.
