Hi Guix,

I am trying to figure out why sbcl-numcl fails to build since the update
to SBCL 2.0.2. See here for a typical build log:

   http://ci.guix.gnu.org/build/2339924/details

What happens is that SBCL runs out of heap space and stops. However, I
can load numcl into SBCL 2.0.2 perfectly well when I load it via ASDF
under my own user account.

Therefore I suspect one of the following three possible causes:

 1. The build daemon runs with memory restrictions that are too severe
    for building binaries for numcl.

 2. Building binaries with SBCL takes more heap space than merely
    loading a system from source via ASDF.

 3. Guix' build systems does something that either limits heap space
    or causes SBCL to require more of it.

Does anyone have an idea on how to proceed to fix the problem?

Cheers,
  Konrad.
