             Bug #: 54001
           Summary: GDB Regression: FAIL: gdb.go/methods.exp: setting
                    breakpoint at main.T.Foo
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
        AssignedTo: i...@airs.com
        ReportedBy: jan.kratoch...@redhat.com

            Target: x86_64-unknown-linux-gnu


20120630 -> 20120701 I see regression PASS->FAIL for FSF GDB HEAD and FSF GCC
HEAD.  Still I am unable to reproduce the PASS case now.

Any FSF GCC 4.8.0 fails for me with:
FAIL: gdb.go/methods.exp: setting breakpoint at main.T.Foo
FAIL: gdb.go/methods.exp: setting breakpoint at (*main.T).Bar

It PASSes with Fedora gcc-go-4.6.3-2.fc16.x86_64.  But I was told FSF GCC Go in
4.6.x is unsupported/broken so I do not have its FSF GCC builds.

GCC 4.6.x PASS case:
(gdb) b 'main.<tab><tab>
main.T      main.T.Foo  main.init   main.main   

GCC 4.8.x FAIL case:
(gdb) b 'main.<tab><tab>
main.Bar.pN6_main.T  main.Foo.N6_main.T   main.init            main.main       
    main.m...@got.plt    main.main@plt        

(GCC 4.7.x behaves like GCC 4.8.x.)
