Bug ID: 69514
Summary: ICE with nested array constructor
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: mrestelli at gmail dot com
Target Milestone: ---
The attached code produces an internal compiler error. Notice that the
problem disappears removing the multiplication 3.0_wp* .
program p
implicit none
integer, parameter :: wp = selected_real_kind(12,307)
real(wp), parameter :: w(2) = &
(/ real(wp) :: 0 , 3.0_wp*(/ real(wp) :: 2 /) /)
!real(wp), parameter :: w(2) = & ! this is fine
! (/ real(wp) :: 0 , (/ real(wp) :: 2 /) /)
write(*,*) w
end program p
