 Hello Bas,

 thank you for your effort.

 I had the same suspicion on HDF5 libraries (yes, they were upgraded 
 too).
 However, after downgrade to libhdf5-8_1.8.13+docs-15 and 
 libhdf5-cpp-8_1.8.13+docs-15
 on my system nothing changed with gdal, i.e. the same error of 
 gdalinfo.
 Besides, NetCDF and HDF5 utils, at least, keep the file format correct 
 recognition,
 see e.g. ncdump -h JEJK_topoC9k_ZABA10mHbpv.nc  or h5topng -d z 
 JEJK_topoC9k_ZABA10mHbpv.nc

 On the other hand, I can just recognize that something in the chain gmt 
 - libgdal - libnetcdf - libhdf5 went wrong recently (Stretch upgrade at 
 the begin of October), it may be somehow related to HDF5 transition.

 The file is a bit large (about 750KB - sorry I have not found a smaller 
 one), so I'll try to attach it to the mail again.
