           Summary: print-stack-trace.cc test case print "Dwarf Error:
                    Info pointer extends beyond end of attributes"
           Product: compiler-rt
           Version: 3.8
          Hardware: PC
                OS: Linux

The error message occurs when we do clang bootstrap testing.

Reproduce Step:

1. Need a bootstrap version of clang

mkdir stage2 && cd stage2

CLANG_PATH=/path/to/clang/built/by/gcc
CC=$CLANG_PATH/bin/clang
CXX=$CLANG_PATH/bin/clang++

cmake -DCMAKE_C_COMPILER=$CC \
      -DCMAKE_CXX_COMPILER=$CXX \
      -DCMAKE_BUILD_TYPE=Release \
      /path/to/llvm/src

make -j8 check-sanitizer

2. Search the binary "print-stack-trace.cc.tmp" and execute it.

find -name 'print-stack-trace.cc.tmp' -exec {} \;

3. Output on x86:
/usr/bin/addr2line: Dwarf Error: Info pointer extends beyond end of attributes
.. (repeat 14 times)

    #0 __sanitizer_print_stack_trace

    #4 _start <null> (print-stack-trace.cc.tmp+0x00000041a2f8)

4. Output on PPC:
/usr/bin/addr2line: Dwarf Error: Info pointer extends beyond end of attributes
.. (repeat 14 times)
