Package: binutils-multiarch
Version: 2.18.1~cvs20071027-2
Followup-For: Bug #438956
I rebuilt binutils with debug symbols and got a more complete backtrace:
(gdb) run -b binary -m arm -D endless
Starting program: /usr/bin/objdump -b binary -m arm -D endless
endless: file format binary
Disassembly of section .data:
0000000000000000 <.data>:

The problem is
(gdb) print *info->symtab
$3 = (asymbol *) 0x0
The upstream CVS has a fix:
http://sourceware.org/cgi-bin/cvsweb.cgi/src/opcodes/arm-dis.c.diff?r1=1.86&r2=1.87&cvsroot=src
I'm just rebuilding to test that patch.
Best regards
Uwe
