The run did not fail with the Release build.

Debug sets -fpe0, so we believe there is a bug within the HDF5 library which causes the exception.

A small (not quite minimal) example to reproduce the problem (Use mpifort -fpe0) :

program nc_open_example
  use netcdf

  implicit none

  integer :: status, fid
  character(len=500) :: filename_nc3,  filename_nc4

  filename_nc4 = '/g/data/ik11/inputs/access-om3/0.x.0/1deg/cice/grid_2024.04.04.nc '
  filename_nc3 = '/g/data/ik11/inputs/access-om3/0.x.0/1deg/cice/grid.nc '

  status = nf90_open(filename_nc3, NF90_NOWRITE, fid)

  write(6,*) nf90_strerror(status)

  status = nf90_open(filename_nc4, NF90_NOWRITE, fid)

  write(6,*) nf90_strerror(status)

  status = nf90_open('link_to_grid.nc', NF90_NOWRITE, fid)

  write(6,*) nf90_strerror(status)

end program nc_open_example

This has been fixed in hdf5 1.14.4 - see https://github.com/HDFGroup/hdf5/pull/3837

[dougiesquire]

The executables in

/g/data/ik11/spack/0.21.2/opt/linux-rocky8-cascadelake/intel-2021.10.0/access-om3-d6813d6b9e1df560ac3f6ba6a605daab9cfd9569_main-q4wfaqb

are built against hdf5@develop-1.14 which includes the above fix.

There are no DEBUG builds in that folder - I guess I would need to do a seperate debug build using those modules from that path ?

I may have misunderstood, when building through spack, the file name doesn't include Release/Debug like building though build.sh. So possibly your executable would have fixed the problem.

This bug may no longer be relevant. With the ACCESS-NRI build, specifying build_type=Debug doesn't flow down to the dependncies. i.e. the Debug flags are only on for compiling the access-om3 code (the bits in this repo and submodules) and not on for compiling hdf5.
