Bug ID: 24981
Summary: Hit assertion failure in ld/ldlang.c:7504
Product: binutils
Version: 2.33 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: romain.geissler at amadeus dot com
Target Milestone: ---
Hi,
I have got a new assertion failure when upgrading in my toolchain binutils from
2.32 branch to the trunk (2.32.51) branch.
The error happens when I try to run gcc test suite. I build gmp/mpc/mpfr in the
gcc tree directly (not really advocated by gcc developers anymore, but it still
works for years), and the issue happens when running the tests of mpfr through
the gcc global "make check".
For now details are sparse, it happened during a CI build, I don't have access
to the artefacts of the build anymore. Logs are showing an assertion error in
ld/ldlang.c:7504

Note that I build gcc (and thus mpfr) using LTO, as it is configured to do a
PGO + LTO bootstrap build.
The asserting code is the one added by this commit:
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff;h=128bf1fe608badb59d27f9c5c8ffb1a6a6d9d811
If you need more details, I can try to reproduce this issue locally, but might
take some time as a gcc LTO + PGO build is quite long.
Cheers,
Romain
