aaah - this description rings a bell ... OpenBSD has some very useful features for configuration of malloc() - and on this particular box it has: G ``Guard''. Enable guard pages and chunk randomization. Each page size or larger allocation is followed by a guard page that will cause a segmentation fault upon any access. Smaller than page size chunks are returned in a random order. and indeed - enabling "G" on another (x86) OpenBSD box of mine causes make check to die there too ....
