Dear Nilesh and Debian Med (cc MAFFT author Katohさん) I have partly tracked down this lamassemble issue. First, I tested lamassemble on x86_64: the tests passed as expected. Then, I recompiled MAFFT after adding "-m32" to CFLAGS, which compiled it in 32-bit mode. Now, the tests in lamassemble/tests/lama-tests.sh do not give the expected results, as you found.
So it seems that MAFFT sometimes outputs different results in 32-bit mode, versus 64-bit mode. I speculate that this is due to floating point calculations, which can produce different results in 32-bit versus 64-bit mode. I think this is because CPUs use "extended precision" in one mode but not the other. This is arguably not a "bug". I guess this must be a frequently occurring issue, how does Debian usually resolve it? Have a nice day, Martin On Mon, Jul 11, 2022 at 3:36 PM Nilesh Patra <nil...@debian.org> wrote: > lamassemble fails its tests on i386 (see here[1]) -- could you fix > accordingly? > > [1]: > https://ci.debian.net/data/autopkgtest/testing/i386/l/lamassemble/22546451/log.gz >
