How to show derived type array pointer content with idb ?

hanswb — Wed, 05 Oct 2005 20:46:24 GMT

Hello,

I'm trying to print the contents of derived type array pointerin the idb debugger:

Linux Application Debugger for 32-bit applications, Version 9.0-12, Build 20050729
...
stopped at [subroutine `MOD1`sub1():38:3 0x0804a168]
     38   write(*,*) 'my_array',s2%int
(idb) print s1%cdata
type dwarf2_array_descriptor
(idb) whatis s1%cdata
character*1 fstring::cdata(:)
(idb) whatis s2%int
integer*4 my_array::int(:)
(idb) print s2%int
type dwarf2_array_descriptor
I only get this 'type dwarf2_array_descriptor' ???
How can I print the real content of the arrays ?
 
I compiled with ifort 9.0.27 with options:
ifort -g -debug extended mod1.f90 pointer.f90
 
source of mod1.f90 is
module mod1
type fstring
  character (len=1), dimension(:), pointer :: cdata => null()
end type fstring
type my_array
  integer, dimension(, pointer :: int
end type my_array
contains
subroutine  sub1
type(fstring) :: s1
type(my_array)  :: s2
integer :: i
  allocate(s1%cdata(30))
  allocate(s2%int(40))
  s1%cdata(1) = 'a'
  s1%cdata(2) = 'q'
  s1%cdata(3) = 'w'
  s1%cdata(4) = 'e'
  s1%cdata(5) = 'r'
  s1%cdata(6) = 't'
  s1%cdata(7) = 'z'
  s1%cdata(8) = 'u'
  s1%cdata(9) = 'i'
  s1%cdata(10) = 'o'
  do i = 1, 40
    s2%int(i) = i
  end do
  write(*,*) 'fstring',s1%cdata
  write(*,*) 'my_array',s2%int
  deallocate(s1%cdata)
  deallocate(s2%int)
  return
end subroutine sub1
end module mod1

This is just a test module. In the real application I get also only

type dwarf2_array_descriptor. But I need to know the contents.

Any help is appreciated.

Hans

Try a more recent version of the compiler and debugger.

I have the same problem as desribed above. The suggested solution does not solve the problem as I have installed the latest compiler and debugger available.

To illustrate I have made a small testcode (16 lines). To reproduce,
compile with options -g -debug extended and set a breakpoint at the end of the code. Run and issue the command:
p AbsDataType

Then the following error should appear:
anarray = type dwarf2_array_descriptor

This problem must be resolved in order to make idb useful for developers.

------------------8<---------------------------------
PROGRAM test
IMPLICIT NONE

TYPE TAbsDataType
REAL, ALLOCATABLE :: AnArray (:)
END TYPE TAbsDataType

TYPE(TAbsDataType) :: AbsDataType

ALLOCATE(AbsDataType%AnArray(2))

AbsDataType%AnArray(1) = 1.0
AbsDataType%AnArray(1) = 2.0

END

Hello,

I reported the issue to Premier Support. They told methey have fixed it.

Hopefully the fix is included in the next release.
