#2793 sbcl 1.2.2 breaks Maxima build

[Peter Simons]

After updating to SBCL 1.2.2, the Maxima 1.33.0 build fails. A complete build log is available at http://hydra.nixos.org/build/13073061/nixlog/1/raw.

The error message from SBCL:

looks to me like an internal error in SBCL, since it doesn't say anything about a problem in the Maxima code. Can you please report this bug to the SBCL developers? I am going to close this report now, assuming that it is an error in SBCL. If it turns out that's not the case, you can re-open this report.
