Problem with nc_put_att in debug mode

[einola]

When using the debugging option I have a crash in nc_put_att because of an un-allocated variable (see below). This only happens when I've exported the environment variable debug = 1.

This doesn't seem to be a big problem, but it makes using ncio in debug mode a pain or even impossible.

I'm on a mac (10.15.7) using gfortran from macports (gcc version 11.2.0 (MacPorts gcc11 11.2.0_1)).

Monaco:ncio einola$ export debug=1
Monaco:ncio einola$ make test
gfortran -w -g -p -ggdb -ffpe-trap=invalid,zero,overflow,underflow -fbacktrace -fcheck=all -I.obj -J.obj -I/opt/local/include -c -o .obj/ncio.o ncio.f90
gfortran -w -g -p -ggdb -ffpe-trap=invalid,zero,overflow,underflow -fbacktrace -fcheck=all -I.obj -J.obj -I/opt/local/include -c -o .obj/ncio_transpose.o ncio_transpose.f90
gfortran -w -g -p -ggdb -ffpe-trap=invalid,zero,overflow,underflow -fbacktrace -fcheck=all -I.obj -J.obj -I/opt/local/include -o test_ncio.x .obj/ncio.o .obj/ncio_transpose.o test_ncio.f90 -L/opt/local/lib -lnetcdff -lnetcdf

    test_ncio.x is ready.

Monaco:ncio einola$ ./test_ncio.x

PS: Thanks for the code - it's a lifesaver!
