My guess is that the address-space randomizer in OpenBSD
has state that needs to be reinitialized after a dump,
much as the Doug Lea allocator needs reinitialization
(see DOUG_LEA_MALLOC-related code). You can verify this
guess by trying that Debian Squeeze build again, but edit
config.h by hand to #define DOUG_LEA_MALLOC 1 before building;
if this works, that's a hint.
You'll have to look at the OpenBSD source to figure it out,
though, I expect. This stuff mutated quite a bit in OpenBSD 4.4,
according to the manual.
