Package: gdb Version: 7.4.1-1.1 Severity: normal Dear Debian folks,
I am sorry if this is a libc6 issue and if I assigned this to GDB
incorrectly.
Wanting to debug an issue in klogd, report #680099 [1], GDB does not
find the debugging symbols for libc6.
$ ps aux | grep klogd
klog 1741 92.4 0.0 2992 1652 ? Rs 09:33 32:03
/sbin/klogd -P /var/run/klogd/kmsg
$ sudo gdb --pid 1741

The right packages are installed though.
$ aptitude search libc6 # descriptions manually removed

/usr/lib/debug/lib/i386-linux-gnu/i686/nosegneg/ld-2.13.so
So GDB should find and use
`/usr/lib/debug/lib/i386-linux-gnu/ld-2.13.so`, should not it?
Might this be related to multiarch changes? Anyway, I have no clue
whatsoever.
Thanks,
Paul
