Expected behavior cprnc should report any differences between the files

System: Gaea

Additional context Add any other context about the problem here.

Is this a C4 vs C5 problem?

[DeniseWorthen]

Only C5 is left now.

[climbfuji]

I am wondering if that particular version of the stack was still built on c4 - but that doesn't make much sense, since c5 is newer and should understand older instruction sets (unless they are entirely different CPUs, amd vs intel for example)

[AlexanderRichert-NOAA]

I'm unable to reproduce this on gaea57 with the given steps (though with a different netcdf file)-- @deniseworthen are you still having this issue, and if so, on what node(s)?

[DeniseWorthen]

I repeated the steps and got the same error message on gaea55 and gaea57. I tried a different set of netcdf files with the same result.

[climbfuji]

Is there anything in your default setup (.bashrc, ulimit, ...) that might cause this difference?

[DeniseWorthen]

I'm cringing. YES. I had my own install of cprnc which I was still aliasing. I thought I had removed it everywhere already. It is now working. I'll close the issue.

[climbfuji]

Glad that it was such an easy fix! Thanks @AlexanderRichert-NOAA for your help on Gaea
