(There is another issue in that thread)
The following program causes an ICE with gfortran in:
==779== Invalid read of size 1
==779== at 0x58B717: gfc_conv_expr_reference (trans-expr.c:4839)
==779== by 0x5A400B: gfc_trans_transfer (trans-io.c:2328)
==779== by 0x565607: trans_code (trans.c:1371)
Reduced (and w/o comments) full test case:
module mytypes
implicit none
abstract interface
function f(x)
real f, x
end function f
! function g(x)
! integer g, x
! end function g
end interface
procedure(f),pointer,save :: f1
! procedure(g),pointer,save :: g1
interface gen
procedure f1!,g1
end interface gen
end module mytypes
!module funcs
! implicit none
! contains
! function f(x)
! real f, x
! f = 3*x
! end function f
! function g(x)
! integer g, x
! g = 3*x
! end function g
!end module funcs
program test
use mytypes
! use funcs, f2=>f, g2=>g
implicit none
! f1 => f2
! g1 => g2
! write(*,*) gen(1)
write(*,*) gen(1.0)
end program test
