Re: segmentation fault occurs when testing strings if one string has a _FillValue assigned but the other doesn't

Jonathan,

This is certainly a problem.

At current, you may try to switch the order of your if statement,
instead of "if(stringA .ne. stringB) then",
try "if(stringB. ne. stringA) then", which will probably bypass your
current problem.

Thanks,
