            Bug ID: 60986
           Summary: Wrong handling of const variables in lambda functions
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: physik3 at gmx dot net

The code in the attachment compiles, but behaves in a strange way. Output is

====
a = 42
b = 0
b = 0
b = 42
====

expected (and achieved if the function is not templated):

====
a = 42
b = 42
b = 42
b = 42
====
