Subject: Dwarf2-related Internal error

Hi all,
I have problems debugging the attached code (real.f) on AMD64 platform.
However the problem doesn't seem to be AMD64-related, but Dwarf2-related
instead and it only happens if it is compiled by the PGI fortran
compiler (beta is available for free download at www.pgroup.com/AMD64).
Debugging the 'real' binary on AMD64/Linux systems leads to GDB internal
error:
$ ../gdb real
GNU gdb 2003-07-08-cvs

Something is wrong in parsing the Dwarf2 .debug_info section -
unfortunately I don't understand the GDB internals in this field.
Could someone help me with it, please?
All relevant files (source, asm, binaries, cores) are available at:

Thanks in advance for any help!
