Hi guix,

While testing a patch re-introducing %build-inputs when cross-compiling
(probably irrelevant to the build failure though), I encountered an ICE
(internal compiler error).  I checked 'dmesg'; it is not an OOM.
I believe I encountered similar errors in the past, though they disappeared
when I retried the build, so this looks like a non-determenistic build
failure.

Greetings,
Maxime

I built it a few times in recent days (from x86_64-linux) and did not
experience this bug (didn’t see it on ci.guix either).  So yes, maybe
it’s a non-deterministic bug?
