[Message part 1 (text/plain, inline)]

Guile 3.0.7 failed to build on the build farm, during the test suite.

There's nothing to link to on ci.guix.gnu.org because Cuirass can't
evaluate Guix without Guile.

I've attached the build log.

I logged in to berlin.gnu.org and tried building the Guile derivation
again. It failed once, then succeeded, then failed a few more times. So
there is some nondeterminism in the test suite.

At least now there is a substitute for it.

Ouch, apologies for that (I did test on all 4 platforms before pushing
and didn’t stumble upon this issue.)

The log you posted is mangled.  Do you have a clearer one at hand?

Yeah.

Thanks,

I downloaded it from here, and it works:

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=48392#5

But now I've attached it uncompressed; it's only 281 KiB.

Hi Leo,

I can’t seem to reproduce it in the Guile build tree, neither with:

  while ./check-guile suspendable-ports.test ; do : ; done

nor with:

  while ./check-guile ; do : ; done

We’ll have to try to gather more info if it comes up again, or see if
there are configs that trigger it more easily.

Thanks,
Ludo’.

It's happening again for the ungrafting evaluation:

https://ci.guix.gnu.org/eval/45377/log/raw (sorry, this log is unhelpful)
https://ci.guix.gnu.org/eval/45377

And Chris Baines sees it in the Guix Data Service too:

http://data.guix.gnu.org/gnu/store/djr1vmhnl8z8yy4ymkszw5srvfmfv943-guile-3.0.7.drv

For now I'm doing something like `guix gc --clear-failures
/gnu/store/...-guile-3.0.7 && guix build /gnu/store/...-guile-3.0.7.drv`
in a loop on the Berlin server.
