Dear HDF community,

The patch in the attached file fixes a memory corruption (double free)
issue in the h5dump utility.

That bug can be reproduced by supplying one existing file and one non
existing file at the command line as you can see below:

$h5dump test/test_filters_be.h5 test/non_existing.h5
HDF5 "test/test_filters_be.h5" {
GROUP "/" {
   DATASET "dset" {
      DATATYPE H5T_STD_I32BE
      DATASPACE SIMPLE { ( 2 ) / ( 2 ) }
      DATA {
      (0): 1, 1
      }
   }
}
}
h5dump error: unable to open file "test/non_existing.h5"
*** Error in `h5dump': double free or corruption (out):
0x00000000006e67b0 ***
Aborted

Best regards,
Reinhard Resch

Thank you for reporting the problem and providing the patch. I created a JIRA issue HDFFV-9639. We will review the patch this week.
