HDF Corruption Problem

A corruption problem has been discovered in the HDF MFHDF (SD) library, which can occur when an SDS and a dimension have the same name. In the HDF 4.2r1 release, one-dimensional datasets can be corrupted. Prior to HDF 4.2r1, both one and two-dimensional datasets could be corrupted.

HDF allows you to create a dimension with the same name as an SDS, although this should not be possible and is a violation of the netCDF model. The corruption occurs when an attribute or a dimension scale is added to the dimension that has the same name as the existing SDS.

Please refer to the HDF 4.2r1 Known Problems page for detailed information on this issue:
https://support.hdfgroup.org/release4/known_problems.html#corrupt

We are working on a fix to correct this problem.


Dropping Support for MSVC++ 6.0 and Dec Visual Fortran 6.6

We would like to drop support for MSVC++ 6.0 and Dec Visual Fortran 6.6. If you would like for us to continue support for these compilers, please notify the HDF Group Helpdesk ( ).
