I'm testing %bootstrap-guile from bootstrap.scm and I'm getting a

bug#34427: [PATCH] build guile-static with guile-2.0

[Efraim Flashner]

[-- Attachment #1.1: Type: text/plain, Size: 365 bytes --]

When experimenting I found that using guile@2.0 as a base for
guile-static, the resulting guile-static didn't segfault on the target
architecture.

bug#34427: guile-bootstrap@2.2 segfault?

[Ludovic Courtès]

Hello Efraim,

Efraim Flashner <efraim@flashner.co.il> skribis:

To be clear, I believe this is for a *cross-compiled* Guile, right?

The natively-built binary on x86_64-linux works fine:

--8<---------------cut here---------------start------------->8---
$ unshare -mrf chroot $(guix build guile-static-stripped) ./bin/guile --version

Since I saw a build failure similar to the one you mention when
cross-building for GNU/Hurd, I’m tempted to think this has to do with
cross-compilation.

Thanks,

That's right, %bootstrap-guile is extracted from $(guix build
--target=powerpc-linux-gnu bootstrap-tarballs)

bug#34427: [bug#34453] [PATCH] build guile-static with guile-2.0

[Ludovic Courtès]

Hi Efraim,

Efraim Flashner <efraim@flashner.co.il> skribis:

> When experimenting I found that using guile@2.0 as a base for

As discussed in <https://issues.guix.info/issue/34427>, I would rather
fix the segfault in 2.2 than move back to 2.0 and effectively delay the
problem.

Cross-compilation to aarch64-linux-gnu works fine:

The problem has to do specifically with powerpc-linux-gnu (this is with
transparent emulation via QEMU+binfmt_misc):

--8<---------------cut here---------------start------------->8---
$ unshare -mrf chroot $(guix build guile-static-stripped --target=powerpc-linux-gnu) /bin/guile

--8<---------------cut here---------------end--------------->8---

Unfortunately I fail to get a backtrace from that core dump.

Efraim, could you get a backtrace on the bare metal?

Besides, if PPC32 is the only platform that has a problem, I think this
bug should not be a blocker.

WDYT?

Here's what I get from strace when running on bare metal. I agree, if
it's only affecting ppc32 we shouldn't have it be a blocker.

We can probably drop it. We'll pick it back up again if/when it comes up
again.

Sorry I wasn’t clear; could you get a backtrace from GDB, as in:

  …/bin/guile
  # segfault
  gdb …/bin/guile core

and then at the GDB prompt:

  bt

I'd removing the important flag since this appears to affect only ppc32
architecture and has been dormant for years.

bug#34427: guile-bootstrap@2.2 segfault?

[Efraim Flashner]

We've moved the bootstrap guile to 3.0 for riscv64 and haven't seen any problems. I think we can just close this one and we'll revisit it if someone else decides to use guile-2.2 for a bootstrap guile and runs into this issue.
