            Bug ID: 16509
           Summary: segfault while compiling
           Product: clang
           Version: 3.2
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: halayli at gmail.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

I get this intermittent segfault while compiling. Running make clean && make
few times resolves the issue. The code compiled is generated by protobuf.
