[netCDF #GFG-507049]: ncdump and ncgen

Ludovic,

Thanks for sending the ncdump output.  With this, I have verified that
you found a bug in ncdump, which still exists in the latest snapshot
release.  We can duplicate the problem with the CDL

netcdf ld {
dimensions:
        time = UNLIMITED ; // (17 currently)
variables:
        float temp(time) ;
        float conduct(time) ;
                conduct:C_format = "%11.6g" ;
        float salinity(time) ;
                salinity:C_format = "%8.4f" ;
        float sndspeed(time) ;
                sndspeed:C_format = "%6.1f" ;
        double density(time) ;
                density:C_format = "%9.6g" ;
        double time(time) ;
data:
  temp = 21.793, 21.79, 21.79, 21.789, 21.788, 21.787, 21.786, 21.786, 21.784,
    21.784, 21.784, 21.784, 21.784, 21.783, 21.782, 21.78, 21.775 ;

 conduct = 0.003, 0.003, 0.003, 0.003, 0.003, 0.003, 0.003, 0.003, 0.002,
    0.002, 0.002, 0.002, 0.002, 0.002, 0.002, 0.002, 0.002 ;

 salinity = 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011,
    0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011 ;

 sndspeed = 1465.1, 1465.1, 1465.1, 1465.1, 1465.1, 1465.1, 1465.1, 1465.1,
    1465.1, 1465.1, 1465.1, 1465.1, 1465.1, 1465.1, 1465.1, 1465.1, 1465.1 ;

 density = 999.146, 999.146, 999.146, 999.146, 999.146, 999.146, 999.146,
    999.146, 999.146, 999.146, 999.146, 999.146, 999.146, 999.146, 999.146,
    999.146, 999.146 ;

 time = 39425.60131802, 39425.60137139, 39425.60142465, 39425.60147788,
    39425.60153113, 39425.60158437, 39425.60163759, 39425.60169102,
    39425.6017441, 39425.60179734, 39425.60185068, 39425.60190388,
    39425.60195706, 39425.60201029, 39425.6020773, 39425.60214675,
}

which when run through ncgen and ncdump shows the trailing "g" characters
you see, but if the attribute
                conduct:C_format = "%11.6g" ;
is deleted, there are no trailing "g" characcters on the values of the
subsequent variables.  We will make finding and fixing this bug a high
priority and let you know when we have a fix.

Thanks for reporting tthe problem!
