addr2line reports wrong line number for abort(), gdb reports correctly

[Sam Roberts]

I'm trying to use the addr2line source as an example of using bfd to map the
addresses from the glibc backtrace() back to file and line number. In the
process I realized that addr2line doesn't report the correct address.

This seems like a bug.

gdb reports:
(gdb) bt
#0  0xffffe410 in __kernel_vsyscall ()
#1  0xb7e989a1 in raise () from /lib/tls/i686/cmov/libc.so.6
#2  0xb7e9a2b9 in abort () from /lib/tls/i686/cmov/libc.so.6
#3  0x0804836b in level_aa () at ab.c:5
#4  0x0804838c in main () at ab.c:10

addr2line:

% addr2line -e ab 0x0804836b
/home/sroberts/s/segv/ab.c:9

% cat ab.c
#include <stdlib.h>

void level_aa()
{
        abort(); /* <- this is line 5, gdb is correct */
}

int main()
{
        level_aa();
        return 0;
}

compiled with:

% gcc -o ab -g ab.c

% /usr/bin/addr2line --version
