Bug #: 57033
Summary: ICE on extended derived type and default
initialization
Classification: Unclassified
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: tiloschw...@gcc.gnu.org
Hi,
with this program
-----------------
program ice
type m
integer i
logical :: f = .false.
end type m
type, extends(m) :: me
end type me
type(me) meo
meo = me(1) ! ICE
!meo = me(1, .false.) ! does work
end program ice
-----------------
I get:
gfortran-4.4: No ICE
gfortran-4.6: No ICE
gfortran-4.7: ICE
gfortran-4.8: ICE
gfortran-4.9: ICE
