[Patch, Fortran, 66035, v1] [5/6 Regression] gfortran ICE segfault

[Andre Vehreschild]

Hi all,

please find attached a patch for 66035. An ICE occurred when in a structure
constructor an allocatable component of type class was initialized with an
existing class object. This was caused by 

- the size of the memory to allocate for the component was miscalculated,
- the vptr was not set correctly, and
- when the class object to be used for init was allocatable already, it was
  copied wasting some memory instead of a view_convert inserted.

All of the above are fixed by the attached patch.

Bootstraps and regtests ok on x86_64-linux-gnu/f21 for trunk and gcc-5-trunk.

Ok for trunk and gcc-5-trunk?

Regards,
	Andre
