Subject: Guix fails to build with libgc 8.0.4
Date: Thu, 25 Jul 2019 20:26:15 +0200

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

Some days ago Guix failed to build on openSUSE Tumbleweed. Today I
started to investigate it.

Guix fails to build on Tumbleweed with `make -j4` or a greater thread
count (see guile_coredump_building_guix.log)

It doesn't fail to build with `make -j3` or less threads and when
building inside of `guix environment --pure guix`.

I then started to look around what could differ between Tumbleweed and
guix environment. My first assumption was kind of hit :)

Tumbleweed is built since some days with libgc 8.0.4 and Guix is still
on 7.6.6. In my home project[0] I have built now Guix (and Guile) with
libgc 7.6.4, the version Tumbleweed used before. Guix builds now with
`make -j4` and greater again on Tumbleweed...

So it seems that guile is not compatible with libgc 8.x yet? Is this
correct?

I wanted to update libgc in guix but it has 5k dependencies, so I did not :P

Any Ideas how to fix this? Do you need any further information from me?

Cheers Jonathan

To isolate the problem, how about:

  1. Defining a Guix package for libgc 8.0.4;

  2. Running “guix build guile --with-input=libgc <at> 7=libgc <at> 8” (or
     defining a package along these lines).

?

Thanks in advance,
Ludo’.

I did this and the build was fine as I expected. Guile builds fine
against libgc-8. But building Guix with a guile-libgc8 goes wrong.

I got now this little patch and try to build guix with:
./pre-inst-env guix build guix -K

So you built Guile (through Guix) against libgc 8.0.4, and then you
tried to use that Guile to build Guix, is that correct?

Thanks,

Yes, that's what I did. So the problem really is with Guile not
supporting libgc 8.0.4...

I think so, yes.

Can you post your patch to the libgc package, though?  It’s weird that
Guile passed its test suite but then crashes when compiling Guix.

I already posted all I have in a previous mail:
https://issues.guix.gnu.org/issue/36811#3

For the openSUSE package I just build guile against libgc 7.6.4

Just for the record: Ludo added libgc-8 in
69961ac3b9db2dbb99abb5c45ff6be3a9c01b5de on master. It's not yet used,
so we need to replace libgc-7.6 with it and see how it goes...

Hi Jonathan,

As discussed yesterday on #guix, I tried this:

  guix build guile3.0-guix --with-input=libgc <at> 7=libgc <at> 8

as of Guix commit 9d0dfd9a9a7c43363a4e140c20d49f119fe6f2e3.  Guile 3.0.0
itself builds fine (test suite included), but the build of Guix crashes
like this (on x86_64-linux-gnu):

Apparently the message and abort come from ‘GC_unmap’ or ‘GC_unmap_gap’
in libgc, but I have no idea what to think about it.  Could it be a heap
exhaustion issue or similar?  That’s not impossible.

Thanks,
Ludo’.

This is exactly the error I see on Tumbleweed and what this issue is
about :) This is good, so I guess it also has the same root somewhere in
guile<->libgc8.

Thanks for providing the reproducer!

With Guile 3.0.1 + the patch for
<https://issues.guix.gnu.org/issue/39266>, the command above succeeds.

Specifically:

  guix pull --commit=e4b5bdf7993590fefeb7182ae71beec4a9f69e3f
  guix build --with-input=libgc <at> 7=libgc <at> 8 guile3.0-guix

Could you confirm that it works for you?

Thanks,
Ludo’.

That's working for me. I built guix with guile 3.0.1 plus the patch from
#39266 and the crash when building guix with more then two threads went
away!

Thank you, Ludovic! Closing this bug now :)
