I've seen this a couple of times before, here and there. The
problem started to happen on debian unstable gcc & co some
time ago. On the surface its caused by some part of the code
trying to free() a pointer allocated with MALLOC(). If the
pointer is freed with FREE(), the problem disappeared in
the cases I encountered -- or was it the other way around
(malloc followed by FREE). Matching the cases may be worth
trying anyway if it turns out to be that. ;)
