!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG
I see the expected geogrid.nc output files but ? Could anyone please explain this bug ? Can it be ignored? I enabled debugging with GNU toolset, and find the SIGFPE occurs.
Why would HDF5/NetCDF trigger this floating point error during init, file create phase?
