Library
-------
+ - Fixed file corruption bug which could write an incorrect number of
+ messages to an object's header under certain circumstances.
+ Generally, the sequence of actions to generate this bug looks
+ like this:
+ - Create an object
+ - Close the file
+ - Re-open the file
+ - Add 2 (or more) attributes to the object
+ - Close the file
+ - Re-open the file
+ - Delete one of the attributes on the object
+ - Add a smaller attribute to the object
+ - Delete the smaller atttribute on the object
+ - Add a larger attribute on the object
+
+ After this, the number of header messages stored for the object
+ will be off by one. Other sequences of modifying attributes on an
+ object could also trigger this bug. If you are opening an
+ object and the bottom few messages of the HDF5 error stack
+ resembles this, the object has been affected by this bug:
+
+ #007: ../../hdf5_v1.6/src/H5C.c line 3887 in H5C_load_entry(): unable to load entry
+ major(08): Meta data cache layer
+ minor(40): Unable to load metadata into cache
+ #008: ../../hdf5_v1.6/src/H5Ocache.c line 332 in H5O_load(): corrupt object header - too few messages
+ major(12): Object header layer
+ minor(40): Unable to load metadata into cache
+
+ Specifically, "corrupt object header" is the best string to search
+ for in the HDF5 error stack output.
+
+ If your files have been affected by this bug, or you are concerned
+ that your files might have been, please contact the HDF Helpdesk
+ at hdfhelp@ncsa.uiuc.edu for a tool to detect and repair files
+ affected by this problem. QAK - 2006/6/16
