Comment (by rhaas):

 Hello Yosef,

 the test now fail, for both SphericalHarmonicReconGen and
 SphericalHarmonciRecon, by triggering the level 0 warning in line 42 of
 NullEvolve/src/NullEvol_InitialSlice.F90. You can see the console output
 here:
 https://build.barrywardell.net/job/EinsteinToolkit/lastCompletedBuild/testReport/(root)/SphericalHarmonicRecon/regression_test_2procs/

 The condition that triggers the error is: {{{abs(zeta(loc_q,loc_p) -
 dcmplx(1.,1.)) .gt. 1d-10}}} and not being an author I cannot judge if
 this is just due to the threshold being too tight or due to something
 else. Note that the test passed when compiled with {{{-O2}}} and without
 {{{--fast-math}}} using gcc 7.2 on my workstation, namely the Recon one
 has
 {{{
   Test SphericalHarmonicRecon: regression_test
     "PITTNullCode/SphericalHarmonicRecon/test/regression_test.par"

   Issuing mpirun -np 2
 /data/rhaas/postdoc/gr/cactus/ET_trunk/exe/cactus_sim
 /data/rhaas/postdoc/gr/cactus/ET_trunk/arrangements/PITTNullCode/SphericalHarmonicRecon/test/regression_test.par

    j_wt[0]_2D.asc: differences below tolerance on 9698 lines



   Success: 4 files compared, 1 differ in the last digits
 }}}
 while the ReconGen one passes identically which is expected since the test
 data was generated on my workstation.

 Would you be able to comment if a difference in 1e-10 for zeta from 1+i is
 something to be concerned about?

 Yours,
 Roland
