h5close fails to update the file on disk

creating a new file that contains a data set and then calling h5close fails to update the file on disk:

library(h5)
f=h5file("bug.h5",'w')
f['a']=1:3
h5close(f)
system("/opt/apps/tools/hdf5-1.10.1/bin/h5dump bug.h5")
h5dump error: unable to open file "bug.h5"

The file appears to be updated correctly after quitting and restarting R,

system("/opt/apps/tools/hdf5-1.10.1/bin/h5dump bug.h5")
HDF5 "bug.h5" {
GROUP "/" {
   DATASET "a" {
      DATATYPE  H5T_STD_I32LE
      DATASPACE  SIMPLE { ( 3 ) / ( H5S_UNLIMITED ) }
      DATA {
      (0): 1, 2, 3
      }
   }
}
}
