Hi Martin,

This has nothing to do with Ubuntu. Computing 32767+1 with Integer(2) is invalid in Fortran.
> PD: I don't know how can I disable the option '-fno-range-check' and internet couldn't help me
If nevertheless you still want to compute 32767+1 with Integer(2), you can do it (and get -32768) by enabling (not disabling) the option '-fno-range-check’ .
Cheers,
Dominique
