The build of the previous version, 3.20-5, which is very similar code, did not have the segfault:

So xmlto seems to fail intermittently on mips64el, even though it
behaves reliably on all the other debian architectures.

Sorry that i haven't been able to debug it further.

Perhaps someone who knows mips64el can debug it better than i can.

For debian revisions of 3.20, failures happened on:

  mipsel-manda-02
  eberlin
        
Also for revisions of 3.20, successes happened on:

  mipsel-sil-01
  mipsel-manda-03
  mipsel-manda-01
