            Bug ID: 64052
           Summary: compilation error "local frame unavailable" appears
                    for some optimization levels
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: eugene at hutorny dot in.ua
              Host: Linux 2.6.32-5-686
            Target: avr

code sample illustrating the issue

Compilation success of the attached example depend on the optimization
settings: with optimize("O0") compilation fails with error _local frame
unavailable (naked function?)_ while with optimize("Os") it succeeds.

Expected behavior -  optimization option has no effect on compilation success
