Hi, During a rebuild of all packages in testing (trixie), your package failed to build on i386. Relevant part (hopefully): The full build log is available from: http://qa-logs.debian.net/2025/04/14/jnr-ffi_2.2.15-2_testing-i386.log All bugs filed during this archive rebuild are listed at: https://bugs.debian.org/cgi-bin/pkgreport.cgi?tag=ftbfs-20250414;users=lucas@debian.org or: https://udd.debian.org/bugs/?release=na&merged=ign&fnewerval=7&flastmodval=7&fusertag=only&fusertagtag=ftbfs-20250414&fusertaguser=lucas@debian.org&allbugs=1&cseverity=1&ctags=1&caffected=1#results A list of current common problems and possible solutions is available at http://wiki.debian.org/qa.debian.org/FTBFS . You're welcome to contribute! If you reassign this bug to another package, please mark it as 'affects'-ing this package. See https://www.debian.org/Bugs/server-control#affects If you fail to reproduce this, please provide a build log and diff it with mine so that we can identify if something relevant changed in the meantime.
Interestingly, although upstream doesn't even run tests on i386 [1], the version in bookworm (2.2.7-1) passed and didn't have issues running the tests on i386 [2]. One of the flagged assertions was introduced on 2.2.15 [3], so I'll have to take a closer look as I don't have data confirming if that test ever passed on i386 in the first place... :( I guess I'm claiming this bug for myself to be worked on in MiniDebConfHamburg [4]
Hello. In addition to what Lucas reported, this package fails to build for me on amd64: 82% of the time on machines with 1 CPU 6% of the time on machines with 2 CPUs so maybe the issue is not about amd64/i386 but about overall speed. I suggest that you try on your normal amd64 system using GRUB_CMDLINE_LINUX="nr_cpus=1". If that does not work please contact me privately, as I can offer a VM where this high failure rate happens consistently. Thanks.
For now I only could come up with a workaround disabling the unit tests in all architectures except amd64. https://salsa.debian.org/java-team/jnr-ffi/-/commit/68b9e6c360b4f27f199af8c564d6ff74d09fa0f2 Upstream doesn't really test on i386. They have support for arm64 but the required dependency is not available in Debian yet. In 1 week or so, I'll take a look at the amd64 failures when running in 1 CPU as reported by Santiago. I'm also observing the tests take too long, making the build time 30-40 mins, this doesn't make sense for a normal size library like this one. Anyway, based on what I find at that point, I'll take a decision to go with the workaround linked above and/or address the other outstanding issue(s).
