[Insight-developers] HDF5 test failing : potential suspect

[Luis Ibanez]

Hi Kent,

The following Valgrind report may be pointing
to a potential suspect on the HDF5 tests failures.

The problem is in the HDF5 operations:

* File Close : H5F_close (H5F.c:1761)
* File Flush : H5F_flush (H5F.c:1690)


which seems to be consistent with the
fact that the problem is related to the
stages of closing a file and opening it
later for verification.
