Hi all:

I found a memory leak, either in the netcdf-4 or HDF5 libs.  To
reproduce it,  run the simple_xy_wr.c example program to create a
file, then open and close it in a loop, monitoring the memory usage
with top.  If the file is created in netcdf-3 (or netcdf-4 classic)

format, the memory usage remains constant. If the file is created in

NETCDF4 format, the memory usage goes up and up.  Here's the simple
program to trigger the leak.  I've attached simple_xy_4.nc and

simple_xy_3.nc - the former will lead to a leak, the latter will not.

Thanks!

I will look at this and let you know when it is fixed in the
snapshot...

Ed:  Any progress on this one?
