[Patch, Fortran, OOP] PR 61767: ICE in generate_finalization_wrapper at fortran/class.c:1491

[Andre Vehreschild]

Hi Janus,

so when I interpret the testcase correctly, than the finalizer should not be
called, right? So adding a call abort() in the Finalize and allocating and
deallocating M in the main program should do no harm, but make the testcase IMO
more feasible. What do you think?
