Comment (by rhaas):

 This is a question for Yosef or one of the other authors. This triggers:
 {{{
 31      ! Note: the extraction WT is at rb(char_nx0+1)
 32      ! start marching at the 2nd point
 33
 34      if ( FirstTime ) then
 35         FirstTime = .false.
 36         if (minval(abs(zeta - dcmplx(1,1))) < 1.0d-10) then
 37            Tarr = minloc(abs(stereo_q(:,1)-1.))
 38            loc_q = Tarr(1)
 39            Tarr = minloc(abs(stereo_p(1,:)-1.))
 40            loc_p = Tarr(1)
 41            if (abs(zeta(loc_q,loc_p) - dcmplx(1.,1.)) .gt. 1d-10) then
 42               call CCTK_WARN(0, " Error ")
 43            endif
 }}}
 in ./NullEvolve/src/NullEvol_InitialSlice.F90 line 42. Ie
 {{{abs(zeta(loc_q,loc_p) - dcmplx(1.,1.)) .gt. 1d-10}}} whatever that
 means. Note that the data has been freshly regenerated using gcc 7.2 with
 {{{-O2}}} but without {{{--fast-math}}} (which may be used on the Jenkins
 machine).

 I will have to try and see if I can reproduce the error on my workstation
 (or dig up my login information for the Jenkins VM machine to play around
 on it).

 Yosef, would you be able to tell if there is anything one can do about
 this error?
