Actually, it dumps core instantly on 32-bit machines too, if they are
pickier about alignment than Intel hardware is. You can't map
structures onto char[] arrays that start at odd byte offsets and not
expect trouble.
I also do not trust macros like this:
typedef struct {int32 len;uint16 numlevel;char data[1];
} ltree;
#define LTREE_HDRSIZE ( sizeof(int32) + sizeof(uint16) )
because they take no account of the possibility of padding between fields.
