Thanks for your help, David.

I take it that you don't see any leak under Windows?

Thanks for pointing out h5_close! I just followed the example files from
the hdf5 documentation, which didn't used h5_close.

If I add an h5_close at the end of ex_read_hdf5 and ex_create_hdf5, I no
longer leak memory. If, however, I just try to h5_close when I'm done
reading in a bunch of files, I still leak.

Adding h5_close, however, doesn't change the problem I am having where
the amount of memory used is many times the size of the file being read
in. The ~40K file I am reading in ends up reading in to about 50 MB of
memory, which is freed by the h5_close. The files are also slower to
read in than I would expect. If I write out a structure with a zero in
it, rather than a nested structure with a zero in it, things read in
quickly and no memory is leaked, even without h5_close.

Thanks a lot,

Eddie Schlafly
