Thanks Jeff!
This is not an ncdump bug; nc_open fails on this file!
I have added it to the netCDF-4 tests and will let you know when I get
it solved...
Thanks,
Ed
OK Ed - thanks for looking into it. I'm running into another potential
bug, probably in the HDF5 lib. I get
H5Oalloc.c:1350: failed assertion `oh->chunk[curr_msg->chunkno].gap == 0'
Abort
when trying to rename a variable in my python script. Haven't been able
to trigger the error in a equivalent C program yet, but if I do I'll
forward it.
