Greetings,

I cannot reach a group within my hdf. I tried h5ls and it cores. The file is 
rather big, so I cannot attach it. Below is the log from gdb. It provides some 
info re program arguments and a version.
The only "unusual" thing about this group is that it contains a vector 
attribute with nan's, but I believe it shouldn't be an issue.
Please advise.

Thanks,

Slava Mazur
