Are you familiar with git? If yes, then you could try and bisect the
issue. You would do something ala:

$ git bisect start
$ git bisect good fio-1.21
$ git bisect bad fio-1.31

and then git would checkout a point in between. You would then compile
and run, checking if it works or not. If the version works, then you
would reply with

$ git bisect good

if not, then you would do

$ git bisect bad

This continues until git tells you which commit is the defective one.
I'll give it a spin on Solaris too, I recently put Solaris 11 on a box
for test purposes.
