Description Rakesh Pandit 2009-04-09 15:23:19 UTC

Description of problem:
pfunct -l --function=_ZN3gnu9classpath5tools7keytool4Main8LIST_CMDE  ./gcc-debuginfo-4.1.2-44.el5.i386/usr/lib/debug/usr/lib/libgcj-tools.so.7rh.0.0.debug

Gave a segmentation fault:

Segmentation fault

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,

Comment 1 Arnaldo Carvalho de Melo 2009-04-09 15:30:53 UTC

Hi, can you please try using the dwarves package in f11-beta/rawhide? It probably fixes this bug, if it does, I'll release an update for f10/f9

Comment 2 Rakesh Pandit 2009-04-10 06:04:03 UTC

Rawhide this one seems to work -- may you push an update?

Thanks!
