This looks like a rounding error in the calculation of the bounds. If
you change the number of levels to 50 a suitable upper bound is found.
shade/lev=50 co_emac
works as expected. The maximum level appears to be calculated as 1.85E-7
rather than 1.90E-7. The symbol LEV_MAX should report this but I see it
as "0" which is rather useless.
LEV_MIN = "0"
LEV_MAX = "0"
LEV_NUM = "29"
LEV_DEL = "0"
My guess is that there is a problem with the number of significant
figures required and the precision available in the 1E-7 neighbourhood.
