--- Comment #1 from janus at gcc dot gnu.org ---
Confirmed with 4.9 and trunk. Slightly reduced test case:
implicit none
type ty_mytype1
end type
class(ty_mytype1), allocatable,target:: cla1
class(*), pointer :: ptr
ptr => cla1
end
The backtrace on trunk is:
c0.f90: In function ‘MAIN__’:
c0.f90:2:0: internal compiler error: Segmentation fault
implicit none
