[Bug fortran/42119] New: internal compiler error: in expand_expr_addr_expr_1, at expr.c:6862

[nvab at ibrae dot ac dot ru]

Test file (Test.f90):
-------------------------------------

module Test
use ISO_C_BINDING

contains

subroutine Callback(arg) bind(C)
  integer(C_INT)  :: arg
end subroutine Callback

subroutine Check(proc)
  type(C_FUNPTR)  :: proc
end subroutine Check

end module Test


program Main
  use Test
  type(C_FUNPTR)  :: proc

  call Check(C_FUNLOC(Callback))

! This works fine:
!  proc = C_FUNLOC(Callback)
!  call Check(proc)

end program Main

-------------------------------------

Compiler output:
