According to Martin Liska, this problem also reproduced building an
--enable-pgo-build=lto libopcodes shared lib prior to the patch I committed,
and disappeared after.

A pity.  Oh well.  As far as I could tell from the build logs you were not
building with -z relro -z now, but if that was the case then the ldlang.c fix
I've just committed (fixing .got/.plt order) is relevant and a plausible fix
for the assertion fail.

Re: PowerPC64 .branch_lt address

On seeing PR29369 my suspicion was naturally on a recent powerpc64
change, commit 0ab80031430e.  Without a reproducer, I spent time
wondering what could have gone wrong, and while I doubt this patch
would have fixed the PR, there are some improvements that can be made
to cater for user silliness.

I also noticed that when -z relro -z now sections are created out of
order, with .got before .plt in the section headers but .got is laid
out at a higher address.  That's due to the address expression for
.branch_lt referencing SIZEOF(.got) and so calling init_os (which
creates a bfd section) for .got before the .plt section is created.
Fix that by ignoring SIZEOF in exp_init_os.  Unlike ADDR and LOADADDR
which need to reference section vma and lma respectively, SIZEOF can
and does cope with a missing bfd section by returning zero for its
size, which of course is correct.

PR 29369
* ldlang.c (exp_init_os): Don't create a bfd section for SIZEOF.
* emulparams/elf64ppc.sh (OTHER_RELRO_SECTIONS_2): Revise
.branch_lt address to take into account possible user sections
with alignment larger than 8 bytes.

(cherry picked from commit 5d471bd907be60e9858b22cdf4fd10ddc0f6ee1a)

Were the toolchain and libraries exactly the same when you tried to reproduce
the fail?  If not, we might have a bug somewhere that only triggers once in a
blue moon.

when trying to collect the object files, I couldn't reproduce this anymore
myself. Closing as invalid.

--- Comment #1 from Alan Modra  ---
The assertion failure is the one at the end of lang_size_relro_segment_1, which
indicates that the reverse layout of sections done there somehow exceeds the
space requirement for the normal forward layout of sections.  I'm not clever
enough to see how this might happen without the objects files.
