Description of problem:


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
SANDER is a molecular dynamics program ( http://ambermd.org/ ) written in FORTRAN 95. I am a developer and recently some new code added to the CVS tree is triggering an ICE. I cannot paste this code here at the moment due to license issues, but I am currently working on an example piece of code that will cause the same issue.


  
Actual results:
[mjw:sander]$ gfortran -c -O0 -fno-second-underscore -ffree-form  -g 
-Wall -o memory_module.o _memory_module.f
_memory_module.f: In function âmory_initâ_memory_module.f:507: internal 
compiler error: in modified_type_die, at dwarf2out.c:8495
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla> for instructions.


Expected results:

Compiles fine

Additional info:

[mjw:sander]$ gfortran -v

Works if one omits the -g flag:

gfortran -c -O0 -fno-second-underscore -ffree-form  -g -Wall -o 
memory_module.o _memory_module.f


This is not being seen with gfortran 4.3.2.
