Working w/ SBCL 1.0.55 + current Git sources (post-5.31). load(lapack) chugs along for a while, then dies with:

I think this is a known issue. It has been reported on quicklisp too. SBCL uses a large amount of memory to compile the lapack library. The default heap size is too small. CMUCL with it's default heap of 512MB can compile it for some reason. I do not know why SBCL requires so much heap. The lisp code itself isn't special, but some of the routines are really large because the original Fortran routine is really large.

Yeah, after searching for the error message, I see it has been encountered before. When I run Maxima with -l sbcl -X '--dynamic-space-size 1728', load(lapack) succeeds (although not with --dynamic-space-size 1024, and with 2048, Maxima won't start). I don't think there's anything to be done in Maxima about this so I'm closing it as wont-fix.
