Some additional information:

GCL does not segfault if I get the substitute from hydra (where Maxima
builds successfully).  It does segfault (on the aforementioned
architectures) if I get the substitute from berlin (where Maxima fails
to build) and if I build it locally.

Here is what I have tried (I get the same results when passing
‘--system=i686-linux’ to the build commands):

--8<---------------cut here---------------start------------->8---
diego <at> GLaDOS ~$ guix gc --delete $(guix gc --list-dead |grep gcl-2) 

[...]

diego <at> GLaDOS ~$ $(guix build --substitute-urls=https://mirror.hydra.gnu.org gcl)/bin/gcl

I have built GCL locally a couple of times and it always segfaults.

My Guix is currently on commit 0bd1498.

Diego
