[Debian-med-packaging] Bug#806675: hmmer: nhmmer fails with fatal exception on armhf

[Andreas Tille]

Hi Sean,

I'd like to forward this issue to you as the hmmer author.  Since in
Debian packages are usually build on several different architectures
sometimes hidden bugs are detected.  Since arm64 and ppc64el might
become relevant in bioinformatics in the not to distant future I'd
consider this issue important.

Any hint would be welcome.

Kind regards

       Andreas.
