--- Comment #34 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
AFAICT the patch fixes all the issues of this PR and its duplicates (I have
found two more). It also compiles the tests in pr55763, but gives a wrong
output

   0.00000000       1.10000002      0.200000003    
  -1.00000000    

instead of

   0.00000000      0.200000003      0.400000006    
  -1.00000000    

for two of them.
