Replying to etourigny:

With much help from Even and Frank, the source of the error message has been found.

It seems that the hdf5 library uses atextit() exit handlers (specifically the function H5_term_library()) which get called before gdal unloads. The call to nc_close (ehich calls H5close()) raises an error because the hdf5 library has been unloaded.

Disabling most of gdaldllmain.cpp seems to solve it temporarily, but a better solution should be found. 

//#ifdef __GNUC__
#ifdef notdef

Not sure if this happens in Windows - adding Joaquim in cc... Can you see if you get the same error?
