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
followedby a guard page that will cause a segmentation fault upon any access. Smaller than page
sizechunks are returned in a random order.
and indeed - enabling "G" on another (x86) OpenBSD box of mine causes
make check to die there too ....
