            Bug ID: 20671
           Summary: Conflicting descriptions of second command line
                    argument (PID/core file) in Debugging with GDB
           Product: gdb
           Version: 7.12
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: jarmo.jaakkola at roskakori dot fi
  Target Milestone: ---

The Debugging with GDB manual is unclear on how the second command line
argument (PID / core file) is handled because the information is provided in
two different places and the passages contain contradictory information. 
According to section 2.1 a core file is tried first, but 2.1.1 says that
attaching to a process is tried first.

Section 2.1 Invoking GDB:

> You can, instead, specify a process ID as a second argument, if you
> want to debug a running process:
>      gdb program 1234
> would attach gdb to process 1234 (unless you also have a file named
> 1234; gdb does check for a core file first).

2.1.1 Choosing Files:

> If the second argument begins with a decimal digit, gdb will first
> attempt to attach to it as a process, and if that fails, attempt
> to open it as a corefile.
