[Bug fortran/34153] New: Unable to debug code compiled with gfortran on MacOSX 10.4.11

["j dot wookey at bristol dot ac dot uk" <gcc-bugzilla at gcc dot gnu dot org>]

Hi,

I'm having a problem using gdb to debug code compiled with gfortran (v 4.3.0).
The code:

      program test
      i = 1
C     Breakpoint here
      end

when compiled with "gfortran -gstabs -o prog prog.f", debugged with "gdb prog"
demonstrates the error. 

The commands:

(gdb) break 3
(gdb) run

produces the output:

> Starting program: /private/tmp/prog 
> Reading symbols for shared libraries .++ done
> 
> Breakpoint 1, main (argc=1, argv=0xbfffe9b8) at ../../../gcc-4.3-20070810/libgfortran/fmain.c:12
> 12      ../../../gcc-4.3-20070810/libgfortran/fmain.c: No such file or directory.
>       in ../../../gcc-4.3-20070810/libgfortran/fmain.c

At this point commands to examine symbols fail:

(gdb) display i
No symbol "i" in current context.

The problem is the same on a PowerPC machine also.
