Bug#819367: gfortran: ICE with -fcheck=mem when initializing an array in a derived type
Package: gfortran
Version: 4:5.3.1-1
Severity: important
Tags: upstream
Dear Maintainer,
I am receiving an internal compiler error (ICE) with gfortran when I
try to compile code that initializes an array (pointer or allocatable)
defined inside a datatype with a scalar value. The problem only
happens with the -check=mem flag.
This is a test code that triggers the error:
--
program test
type tt
real(8), allocatable :: aa(:)
end type tt
type(tt) :: cc
allocate(cc%aa(1:10))
cc%aa = 0.0_8
end program test
--
This is the compilation line:
gfortran -fcheck=mem array.f90
and the error message:
--
array.f90:11:0:
cc%aa = 0.0_8
1
