Harvey:

As I understand it, the case you got a core dump on was a get_vara or
put_vara of scalar variable.

At any rate, code inspection shows that the released netcdf-3.1a
has an error in that it is attempting to check the 'edges' argument
for scalar variables. It should just ignore this argument (and the
'begin' argument) for this case.

At the end of this message find a patch to putget.m4.
