Comment(by phk):

 Sorry about the delay in getting to this.

 I don't have an arm platform to test this on, so I'm a little bit
 handicapped with respect to reproducing the bug.

 I am pretty certain that the TAILQ_LAST macro works in FreeBSD on the arm
 platform, so I am not quite sure what to make of this panic.

 It is true that TAILQ_LAST does some non-nice pointer-gymnastics, but as
 far as I know, they are strictly pointer to pointer, so they should be
 safe.

 Can I get you to pull down a -trunk source tree, and use the autoconf.des
 file and see what happens then ?
