Bug ID: 105372
Summary: The result of the merge function is different when
it's type of parameters is the extensions type of
derived type
Product: gcc
Version: 11.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: xudong.luo@compiler-dev.com
Target Milestone: ---
Whether the mask is a constant or a variable causes inconsistent results of the
merge function when it's type of parameters is the extensions type of derived
type.
1.The mask is constant
Program test00
Type t
Integer :: c
End Type
Type,Extends(t) :: t2
Integer :: c2
End Type
Class(t),Allocatable :: x,y,r
logical :: ok = .true.
x = t2(1,-1)
y = t2(2,-2)
r = merge (x,y,.true.)
Select Type (z=>r)
Type Is (t)
print *,z%c
Type Is (t2)
print *,z%c,z%c2
End Select
End Program
2. The mask is variable
Program test01
Type t
Integer :: c
End Type
Type,Extends(t) :: t2
Integer :: c2
End Type
Class(t),Allocatable :: x,y,r
logical :: ok = .true.
integer :: i = 1
x = t2(1,-1)
y = t2(2,-2)
r = merge (x,y,i == 1)
Select Type (z=>r)
Type Is (t)
print *,z%c
Type Is (t2)
print *,z%c,z%c2
End Select
End Program
