Hi Andrew,
I got these problems when some HDF5 calls were issued after the HDF5
library
was closed. That was mainly a problem with C++, dynamic libraries and
global
destructors. The HDF5 library uses an atexit() call to register a cleanup
routine at termination of the main() routine, and after that there must be
no
call to HDF5 functions any more.
It may also be an indication of memory corruption, but that is even
harder to
trace down. A difference among Linux and Windows appears to be
initialization
of newly allocated memories by zero's or not (from malloc() ), so might be
related to uninitialized RAM.

Hi Elena,
For some reason library cannot shutdown different interfaces (R -
references, E -error, G - group, etc.).
Which version of HDF5 do you use?
I've tested it with HDF5 1.8.4 and 1.8.5 so far.
This error may indicate a bug in the HDF5 library or in the application
;-)
Having an example (in any language) that reproduces the problem will
definitely help.
Yes. :) Unfortunately what happens is that I run the entire test suite
for my package (~200 tests, each of which makes dozens or hundreds of
calls to HDF5), and then when I exit this crops up.
What application-level things could be responsible for this? I am
registering callbacks with the H5E and H5T interfaces, but these don't
seem to be the problem... if I register them and then exit without
doing anything else, it doesn't print the message.
Thanks,
Andrew
