Thanks, Andrew.

Great! With the latest gdb from the trunk, it is ok. 

(gdb) b sub
Breakpoint 1 at 0xa58: file /home/guojiufu/temp/gdb.f90, line 9.
(gdb) b 17
Breakpoint 2 at 0xafc: file /home/guojiufu/temp/gdb.f90, line 17.
(gdb) r
Starting program: /home/guojiufu/temp/gdb/binutils-gdb/arg1.exe

Breakpoint 1, 0x0000000100000a58 in sub (a=..., n=10) at
/home/guojiufu/temp/gdb.f90:9
9       subroutine sub (a, n)
(gdb) c
Continuing.

Breakpoint 2, sub (a=..., n=10) at /home/guojiufu/temp/gdb.f90:17
17        write (*,*) a
(gdb) p a
$1 = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
(gdb) 

So, it seems not to be an issue from GCC, and works fine on with the latest
binutils.

Thanks all!
