Compilation issues with gfortran

[amegann]

I recently installed https://github.com/meom-group/CDFTOOLS on the Jasmin platform here in the UK. When I tried to compile this with key_CMIP6, this error came up:

& (/'uo','vo','wo','zos',(' ', ji=jp_sqdvarmax-5,jp_sqdvarmax) /)
1
Error: Different CHARACTER lengths (2/3) in array constructor at (1)
11:25
& (/'zos','thetao',(' ', ji=3,jp_cubvarmax) /)
1
Error: Different CHARACTER lengths (3/6) in array constructor at (1)

According to stackoverflow, the F90 standard says you are not allowed to have character strings of different lengths in a declaration like this. It seems gfortran insists on this to the letter, while ifort is more tolerant. I padded out the short strings in both cases so that they were all the same length, and this compiled successfully. Is this a known feature of this release?
