Most likely, this crash is due to the use of new progress report feature
in (guix git). If I arrange to not use it, clone the whole repo
proceeds without crashing.
Unfortunately I=E2=80=99m unable to get a usable backtrace once SIGILL has =
been
raised, be it by attaching to it (using
CRASHSERVER=3D/servers/crash-suspend), spawning it and crashing it from
gdb, or inspecting its core file. At best I can see the backtrace of
the msg thread, nothing more:

(Would be nice to fix this debugging issue. It looks like GDB fails to
interpret the thread state of suspended threads or something.)
Anyway, this crash could be due to a GC issue, in which case it would
not be Hurd-specific. I could not reproduce it with i686-linux =E2=80=98gu=
ix=E2=80=99
though, and obviously not with x86_64 binaries either.

Yes, you're right. I've made another release (1.0.9), where I use
(environment '(guile) '(bytestructures guile numeric-data-model))
for the 'base-environment' binding in case we're running on Guile.
It now gives me correct results locally (woe on me for not having
properly tested the previous one) so I think it should definitely work
when cross-compiling too, since the 'eval' is sure to be executed at
run-time and not compile-time...
Fingers crossed, I hope I don't waste your time this time!

I confirm that the attached patch for Bytestructures solves the problem
(running =E2=80=98guix pull=E2=80=99 in my childhurd :-)).
Let=E2=80=99s see whether it needs to be adapted for inclusion upstream.

Hello!
You might have seen that =E2=80=98guix pull=E2=80=99 doesn=E2=80=99t work i=
n your childhurd:
--8<---------------cut here---------------start------------->8---
Updating channel 'guix' from Git repository at 'https://git.savannah.gnu.or=
g/git/guix.git'...
guix pull: error: Git error: invalid version 0 on git_proxy_options
--8<---------------cut here---------------end--------------->8---
This is due to an ABI breakage whereby the Guile-Git code
(cross-compiled from x86_64-linux) fills in the =E2=80=98fetch_opts=E2=80=
=99 member of
=E2=80=98git_clone=C2=A0options=E2=80=99 offset by one word.
On closer inspection, the problem is:
--8<---------------cut here---------------start------------->8---
scheme@(git structs)> (bytestructure-descriptor-size (bs:struct `(("x" ,(bs=
:pointer uint8)) ("y" ,size_t))))
$20 =3D 12
scheme@(git structs)> %host-type
$21 =3D "i586-pc-gnu"
--8<---------------cut here---------------end--------------->8---
Compare with the correct answer:
--8<---------------cut here---------------start------------->8---
$ guix environment --ad-hoc -C -s i686-linux guile guile-bytestructures --=
guile
[...]
scheme@(guile-user)> ,use(bytestructures guile)
scheme@(guile-user)> %host-type
$1 =3D "i686-unknown-linux-gnu"
scheme@(guile-user)> (bytestructure-descriptor-size (bs:struct `(("x" ,(bs:=
pointer uint8))("y" ,size_t))))
$2 =3D 8
--8<---------------cut here---------------end--------------->8---
More specifically, the size of =E2=80=98size_t=E2=80=99 is wrong, but point=
er size is
right:
--8<---------------cut here---------------start------------->8---
scheme@(git structs)> (bytestructure-descriptor-size size_t)
$27 =3D 8
scheme@(git structs)> (bytestructure-descriptor-size uintptr_t )
$28 =3D 8
scheme@(git structs)> (bytestructure-descriptor-size (bs:pointer uint8))
$29 =3D 4
--8<---------------cut here---------------end--------------->8---
=E2=80=98numeric.scm=E2=80=99 in bytestructures reads:
--8<---------------cut here---------------start------------->8---
(define arch32bit? (cond-expand
(lp32 #t)
(ilp32 #t)
(else #f)))
;; =E2=80=A6
(define uintptr_t (if arch32bit?
uint32
uint64))
(define size_t uintptr_t)
--8<---------------cut here---------------end--------------->8---
But (bytestructures guile numeric-data-model) has this:
--8<---------------cut here---------------start------------->8---
(define data-model
(if (=3D 4 (sizeof '*))
(if (=3D 2 (sizeof int))
'lp32
'ilp32)
(cond
((=3D 8 (sizeof int)) 'ilp64)
((=3D 4 (sizeof long)) 'llp64)
(else 'lp64))))
(cond-expand-provide
(current-module)
(list architecture data-model))
--8<---------------cut here---------------end--------------->8---
The problem is that the =E2=80=98cond-expand=E2=80=99 used to define =E2=80=
=98arch32bit?=E2=80=99 is a
expansion-time thing when (cross-)building Bytestructures itself, so
it=E2=80=99s incorrect from cross-building from 64-bit to 32-bit.
I believe that changing it to:
(define arch32bit? (memq data-model '(ilp32 lp32)))
would fix it because then the test would happen at run time.
(Note that Guile-Git uses only the procedural layer of Bytestructures.
The syntactic layer is likely not cross-compilation-capable for similar
reasons.)
To be continued=E2=80=A6
Thanks,
Ludo=E2=80=99.
