Comment (by pramsey):

 Well, I spent a great deal of time getting an emulated MIPS environment
 set up but I cannot replicate the crasher at tickets.sql #2985.
 Also, annoyingly, using nan("0") to get a formatted nan value, the MIPS
 version returns 000000f47f while the intel one returns 000000f87f. The
 both pass "isnan" tests fine, but that doesn't fix the hex-level checks
 for equivalence. It might be better just to drop the POINT EMPTY tests or
 replace them with something like
 {{{
 select st_isempty('010100002001000000000000000000f87f000000000000f87f');
 select st_isempty('010100002001000000000000000000f47f000000000000f47f');
 }}}
 which just checks that a couple different NAN representations still get
 read as nan and interpretted as POINT EMPTY
