            Bug ID: 16768
           Summary: Clang 3.3./Sanitizer: malformed blacklist causes panic
           Product: compiler-rt
           Version: unspecified
          Hardware: Other
                OS: MacOS X

Working with Clang 3.3 on Mac OS X 10.8.3 (x64).

Testing sanitizer blacklist to suppress findings.

I wanted to see how the tool would respond with an empty/malformed blacklist
file.

In the case below, the blacklist file has one entry of just "fun:", without the
CRLF:

  riemann::cryptopp$ cat clang_sanitize_ignore.txt 
  fun:riemann::cryptopp$ 

~~~~~
