Comment (by SimonKing):

 Actually I realise that I made a severe mistake all the time.
 `concat_biseq` returns a pointer to a local variable, and I did so in
 order to make it possible to propagate errors (by saying `... except
 NULL`). But returning a pointer to a local variable can not possibly work.

 Since I want to propagate errors, I suppose it will be better to
 consistently work with pointers. I'll rewrite the module accordingly...
