ERROR: INCORRECT INTEGER VALIDATION

Hi - first post here!

I am building HDF5 1.10 release 5 on Linux, using the “hdf5-1.10.5.tar.gz” download. The library seems to build successfully, and I get PASSED for all tests, except one:

**Data offset with user block * FAILED ***

What could be the cause for this? Is there a workaround? Is this a show stopper?
Thanks!

Additional information: this error occurs in the FORTRAN tests section. The exact message is:
ERROR: INCORRECT INTEGER VALIDATION h5dget_offset_f
Read different values than written.
