Erm...  With a little help, I found the problem (and posted on my other
thread) and it seems like my code should've bombed on Solaris too (as I
was trying to free the same memory twice -> Remove calls Clear, which
frees Orphan and sets the list pointers to null, then it jumps back to
Remove, which tried to free Orphan again).  Any thoughts?

(thanks for trying my code, though :)
