The problem popped up when trying to create a native port of OGo (http://www.opengroupware.org) to FreeBSD. Specifically, certain returned memory should be nil (0), but in fact is 0xd0d0d0d0. I don't know what this pattern stands for, could that be some memory marked as being freed previously? I grepped the FreeBSD 5.1-CURRENT sources but the only valid code reference I came across that seems to deal with the same kind of problem is in /usr/src/sys/geom/geom_subr.c:514: KASSERT(cp != (void*)0xd0d0d0d0, ("ARGH!")); I have no idea what this is all about, I can only guess that it has to do with previously freed memory. Any hint (or pointer to a better suited mailing list) is appreciated.
