Package: gdb
Version: 7.12-6+b1
Severity: normal

Dear Maintainer,

gdb incorrectly parses /proc/pid/cmdline, stopping at the first NUL byte encountered with a warning.

* Steps to reproduce:

$ gdb --args /bin/ls -l
Reading symbols from /bin/ls...(no debugging symbols found)...done.
(gdb) b _start
Function "_start" not defined.
Breakpoint 1 (_start) pending.
(gdb) r
Starting program: /bin/ls -l

Breakpoint 1, 0x00007ffff7dd9090 in _start () from /lib64/
(gdb) info proc
process 5618
warning: target file /proc/5618/cmdline contained unexpected null characters
cmdline = '/bin/ls'
cwd = '/homes/parras'
exe = '/bin/ls'

This happens for all command lines with arguments.

The bug has already been fixed quite some time ago:
Not sure why the Debian version still has it...
