Cool. Even if ghemical seems to be the only caller of that routine right
now, it crashes in libmopac7-1gf so reassigning there.
Can you maybe try to install the old libmopac7-1gf_1.15-4 from squeeze
(if that installs fine still) and see whether you can reproduce it with
that? Installing the testing/unstable version on stable does not
work due to missing dependencies.
