            Bug ID: 65309
           Summary: [Regression] Executes wrong function inside an
                    anonymous namespace on runtime
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: albert.astals at canonical dot com

To be honest the summary is probably wrong, not much of a compiler expert
myself

I have this code that when compiled with gcc 4.9.2 and -g fails but works with
-O2 (also works with 4.8.2 whenever the flags used)

Fails when printing:
a.cpp
a.cpp

Works if printing:
a.cpp
b.cpp

This is affecting Qt since this is reduced test case from Qt sources

$ gcc -v
