When compiling the sample program, gfortran 4.5.0 (referring to Revision
v153847)
the running of it triggers a seg fault due to an optional argument, which was
not present in the beginning, but astonishingly is when calling the
corresponding subroutine:
$ ./test_case
 model_set_particle_data:  present(name) =  F
 particle_data_set: present (name) =  T
Segmentation fault (core dumped)
