Tested all versions with gcc-13 and dev-libs/librdkafka-1.8.2 with gcc-12. The asm should not be trying to use amd64 registers on arm64 Reproducible: Always Steps to Reproduce: 1. emerge random version of dev-libs/librdkafka on arm64 2. read the build log. 3. Actual Results: dev-libs/librdkafka fails to build Expected Results: The build system does not use amd64 registers on arm64 Pi4_GCC-12 ~ # emerge --info Portage 3.0.44 (python 3.10.10-final-0,

Also ran into this on ppc, looks like it's a repeat of https://github.com/confluentinc/librdkafka/issues/1290 . Except this time it's LTO's fault, it optimizes out the dead code so the test passes when it shouldn't. Removing LTO fixes.

It was reported in 2019, and upstream first responded to the report 3 years later, in order to say: > Closing due to inactivity, does not seem like a common issue. The project is aptly named. For a humorous writeup on the topic, see https://0ver.org/#apache-kafka
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=77daa955c05041001df330ba94144b1e5dcc8112 commit 77daa955c05041001df330ba94144b1e5dcc8112 Author: Eli Schwartz <eschwartz@gentoo.org> AuthorDate: 2024-09-06 04:59:23 +0000 Commit: Eli Schwartz <eschwartz@gentoo.org> CommitDate: 2024-09-06 05:03:32 +0000 dev-libs/librdkafka: mark as LTO-unsafe Upstream has an innovative bug report strategy. Wait for people to report bugs in the software, then ignore the bug report for several years, then show up and as the very first official reply: > Closing due to inactivity, does not seem like a common issue. We can presume that this will never be fixed. Although the nuance of whether it is broken depends on the exact architecture used, it is not worth figuring out where it is safe to use for such a, well, *kafkaesque* bit of software. :) Bug: https://github.com/confluentinc/librdkafka/issues/2426 Closes: https://bugs.gentoo.org/895464 Signed-off-by: Eli Schwartz <eschwartz@gentoo.org> dev-libs/librdkafka/librdkafka-2.2.0-r1.ebuild | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-)
