Comment 10 for bug 559253

Please attach full build logs.

I don't know why it took me so long to spot this, but these errors are not from building the contribs, but from building the documentation.

Obviously SBCL breaking like this when building the docs is a sign of something seriously wrong. Seriously wrong can mean anything from a bug in CheneyGC to faulty RAM on your build host.

Are the errors consistent? If you do the same build ten times in a row, are the results the same? If not, something is probably broken in the build environment.
