A simple example that reproduces the error goes a long way. I can't follow your description. Please include a description of your environment (OS, compiler, etc.) The error message suggests that you are using MPI. Are you using parallel HDF5? If so, how?

Checks we have done: 1 - manually write the string and with .compare, this manual string matches exactly the string we have read from an xml buffer. 1a - the manual string can be written to an attribute 1b - the original string raises an error when we write 2 - we have used .copy to make a new copy of the string from the xml buffer 2a - this copy also fails to write with the same error 3 - we removed all new-line characters from the string - this did not help 4 - we tried the .substr method to chop the string to small pieces, this also did not help (all pieces failed to write) 5 - we tried the first 5 characters of the string, which do not have any special characters - still fails The fact that 1a succeeds means we are probably missing something simple. The error is HDF5-DIAG: Error detected in HDF5 (1.8.16) MPI-process 1: #000: H5A.c line 334 in H5Acreate_by_name(): no attribute name major: Invalid arguments to routine minor: Bad value I am hoping someone here has had and fixed the same problem, as we are very stuck.
