[Mingw-users] How to print fortran allocatable array in GDB?

[孔涛 <ka...@ye...>]

Hi, everyone. How to print fortran allocatable array in GDB?  For example, the source file reads
--
program main
implicit none
real,dimension(5) :: a
real,dimension(:),allocatable :: b

allocate(b(10) )

call random_number(a)
call random_number(b)

deallocate(b)
end program

--
I use 'gfortran -g arr.f90 ' and use 'gdb ./a.exe' Then I got the following debug info
---------------------------------
(gdb) b 6
(gdb) b 10
(gdb) r
Starting program: D:\Documents\Projects\test/a.exe
[New Thread 6844.0x1a40]

Breakpoint 1, MAIN__ () at array.f90:6
6       allocate(b(10) )
(gdb) p a
$8 = (3.76478451e-039, 1.54142831e-044, 1.03794626e-038, -nan(0x7ffffe), 0)
(gdb) p b
$9 = (0)
(gdb) c
Continuing.

Breakpoint 2, MAIN__ () at array.f90:11
11      deallocate(b)
(gdb) p a
$10 = (0.997559547, 0.566824675, 0.965915322, 0.747927666, 0.367390871)
(gdb) p b
$11 = (0)
(gdb)
----------------------------------------

So why? How to show the variable b?
