           Summary: lto1: ICE with extern on static linkage
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal

Compiling the attached file

g++ -O0  -flto foo.cc
lto1: internal compiler error: in lto_record_renamed_decl, at
lto-section-in.c:330

removing the external declaration for f4() makes the test pass.
