and yes eax/reg 68 (or n) is dead after the compare in combine:
(insn 37 36 39 3 (parallel [
(set (reg/v:SI 68 [ n ])
(minus:SI (reg:SI 71)
(reg/v:SI 66 [ med ])))

This is a partial regression from 2.95.3 and 3.3.3, 3.2.3 and 3.0.4:
where we had:
subl 28(%ebp),%eax
jne .L7
...
.L7:
testl %eax,%eax
jle .L8
