I'm working on adding h5py python bindings for the H5DS API. The work is nearly complete, nearly all of the unit tests I have assembled so far are passing. However, if I have a 3-dimensional dataset, and I do the equivalent of:
H5DSset_label(did, 0, 'x') H5DSset_label(did, 2, 'z') When I try to determine the length of the label, so I can allocate a buffer of the appropriate length, I have no problem for the x or z dimensions: size = H5DSget_label(did, 0, NULL, 0) but when I try to determine the size for dimension 1, which has no label, I get a segfault: size = H5DSget_label(did, 1, NULL, 0) If I explicitly set dimension 1's label with H5DSset_label(did, 1, ''), then the above call to H5DSget_label works as expected. I'm sorry, I have zero experience writing C programs, so I haven't been able to produce an example in C that reproduces the problem. I suspect the problem may be related to the line in H5DS.c: nbytes = strlen(buf[idx]); but I could be wrong.
