Created attachment 5108
  --> http://sourceware.org/bugzilla/attachment.cgi?id=5108
Fix for the case insensitivity part.

With this patch GDB no longer crashes on internal error.

Still it displays incorrectly:
$3 = (REF TO -> ( character*16 )) @0x31677261: <error reading variable>

which is IIRC due to invalid DWARF produced by iFort but I would have to
recheck it.

Why don't you use gfortran?

Hi Jan,
   To your question, our user believes that the Intel Fortran compiler produces
faster code than does gfortran.

   Would this change that was just made go into the 7.3.50 release of gdb?

Hmm, OK...

We are now at 7.2.50.* snapshots, that will become one day 7.3.  This patch is
now being evaluated, it is not yet checked-in the trunk.

The `REF TO ->' / `<error reading variable>' problem is fixed by:
[new testcase] Regression 7.1->7.2 for iFort [Re: [RFA-v2] dwarf debug format:
Support DW_AT_variable_parameter attribute]
http://sourceware.org/ml/gdb-patches/2010-11/msg00084.html

so `str1' can be printed now with both patches:

(gdb) p str1
$1 = ' ' <repeats 16 times>
[...]
(gdb) p str1
$2 = 'arg1', ' ' <repeats 12 times>
