I wonder how we could keep this finding to other packages. I bet it

Hi,
I tried to narrow down what broke clustalo on mipsel.
The test from 1.2.4-5 passes with the binary in buster,
but not when rebuilding it in buster.
gcc versions:
7: works
8: broken
9: broken
10: broken
clustalo in buster was built with gcc 7, a rebuild with the gcc 8 now in
buster would

thanks a lot for this analysis. Any chance that somebody could
turn this into a patch I could try?
Kind regards

Hi,
as it can be seen on the recent build log of clustalo on mips[1] the
build fails with

# this will work as well

Hi,
I took over the test done by biopython into the clustalo build time and
autopkgtest. As Peter assumed this is an issue in clustalo as you can
see
I agree this is most likely a clustalo error. I think the first two
examples use
temporary input files created during the Biopython tests. However, the third
failing example ought to be useful in isolation:
clustalo -i Fasta/f002 --guidetree-out temp_test.dnd -o temp_test.aln
--outfmt clustal --fo
