            Bug ID: 28027
           Summary: abilint: "Unknown file type given in input" error
                    message has no end of line character (LF)
           Product: libabigail
           Version: unspecified
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: default
          Assignee: dodji at redhat dot com
          Reporter: pabs3 at bonedaddy dot net
                CC: libabigail at sourceware dot org
  Target Milestone: ---

I noticed while playing with abilint that the "Unknown file type given in
input" error message has no end of line character (LF or \n), so if you are
passing multiple files to abilint via xargs, you get all the output on one
line. As far as I can tell all the other errors printed by abilint contain and
end of line character (\n).

$ echo foo > foo
$ abilint --noout foo |& hd
00000000  61 62 69 6c 69 6e 74 3a  20 55 6e 6b 6e 6f 77 6e  |abilint: Unknown|
00000010  20 66 69 6c 65 20 74 79  70 65 20 67 69 76 65 6e  | file type given|
00000020  20 69 6e 20 69 6e 70 75  74 3a 20 66 6f 6f        | in input: foo|
0000002e
$ echo foo | hd
00000000  66 6f 6f 0a                                       |foo.|
00000004

$ grep -B2 -A1 'Unknown file type given in input' tools/abilint.cc
        case abigail::tools_utils::FILE_TYPE_UNKNOWN:
          emit_prefix(argv[0], cerr)
            << "Unknown file type given in input: " << opts.file_path;
          return 1;

--- Comment #1 from Ucel Sani <ucelsanicin at yahoo dot com> ---
On further thought, we shouldn't be encouraging palindromish REs in the manual,
so that naive users aren't drawn into this mess. So I installed the attached
further patch to the documentation.

Of course it would be better to fix the back-reference bugs but this is low
priority and I doubt whether anybody has the time.

hen printing an object of the type sca_port_base - part of the Open Source
SystemC AMS Simulator - gdb versions newer than > 7.6.1 crash (Linux and
MinGW64  versions). Below you find the backtrace when debugging gdb 7.11. The
error occurs in value.c of gdb

We can provide also an executable to reproduce the crash, however it is quite
large, due to the libraries required. Attached you find the source code of the
object which is tried to be printed. GDB commands executed in the session are
