Package: python-tables
Version: 2.3.1-3
Severity: important

Hi,

At a customer, a problem was found with python-tables where, if a file
was opened twice, the second (and subsequent) time(s) python-tables
would return junk.

See attached test case. Run like so:

wouter@carillon:~$ python
Python 2.7.6 (default, Mar 22 2014, 15:40:47) 
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import bugTesting as b
>>> b.bugTest('bugged_file.h5')
[208 135 150   2   0   0   0   0 128 230]
[0 0 0 0 0 0 0 0 0 0]
[0 0 0 0 0 0 0 0 0 0]
>>> b.bugTest('bugged_file.h5')
[112  22 157   2   0   0   0   0 128 230]
[0 0 0 0 0 0 0 0 0 0]
[208 201 160   2   0   0   0   0   0   0]
>>> b.bugTest('bugged_file.h5')
[112  22 157   2   0   0   0   0 128 230]
[0 0 0 0 0 0 0 0 0 0]
[208 133 159   2   0   0   0   0   0   0]
>>> 

On an i386 machine the output of the above is the same every time, as
one would expect. On a machine running the amd64 port, however, this is
not the case.

While I'm filing this bug report on my laptop (which runs unstable), the
customer in question is running stable and has seen the same problem.

Regards,

It works fine with hdf5 1.8.13 currently in testing.
Closing. Feel free to re-open in case you think it's not fixed.
