Description of problem:

Debuginfo rpm is EL5 based gcc debuginfo package: /home/rakesh/gcj/debug/gcc-debuginfo-4.1.2-44.el5.i386.rpm

I was checking for signature of symbol name _ZN3gnu9classpath5tools7keytool4Main8LIST_CMDE 

Dwarves package:  dwarves-1.6-1.x86_64

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


How reproducible:
With above command

Steps to Reproduce:
1. Extract above gcc-debuginfo files
2. Run this symbol which I got from libgcj-tools.so on the corresponding ELF file non-stripped one from debuginfo
3.
  
Actual results:
Segmentation fault

Expected results:
Signature

Additional info:
I had a look at code base a bit. I guess at 'static struct tag *__die__process_tag' switch (dwarf_tag(die)) does not handle class_type. I don't this would be of any help.

If more info is needed, feel free to ping.

Thanks,
