I recollect seeing this with other codes too, which suggests it is an
optimization bug in icc.  I've explicitly included John since I bet they
have seen this at TACC as well.

John put the --disable-vsmoother in there to work around icc with
optimization, but I use icc so infrequently I was always forgetting the
option.  Invariably, I'd run ./configure ; make and then get sidetracked -
coming back much later and icc would still be churning on that file. So I
put in the compiler pragma.
