"Nothing new" for me and you, perhaps.  But I'm not sure about Óscar.

I'm quite sure I've bumped in the past into a bug triggered by a call
to malloc from a library function which had nothing to do with
relocatable blocks.  The bug happened because that malloc call caused
buffer text to be relocated.  Maybe the implementation changed since
then, though.
