| This indeed looks wrong - and could lead to real memory corruption

And if it is wrong, it would be interesting to know wheter we already
have PRs related to that memory corruption -- but I guess it would be
hard to know :-)
Parenthetically, I was wondering who is freeing those extensive
regions of storage xmalloc/xcalloc()ed here and there?
