<pre>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$
~~~~~
Last login: Thu Aug 1 00:45:35 on ttys000
riemann::cryptopp$ make cryptest.exe CXX="/usr/local/bin/clang++
-fsanitize-blacklist=clang_sanitize_ignore.txt -fsanitize=address
-fsanitize=undefined -fno-sanitize=vptr"
/usr/local/bin/clang++ -fsanitize-blacklist=clang_sanitize_ignore.txt
-fsanitize=address -fsanitize=undefined -fno-sanitize=vptr -DNDEBUG -g -O2
-DCRYPTOPP_DISABLE_ASM -pipe -Wno-tautological-compare -c 3way.cpp
fatal error: error in backend: malformed blacklist line: fun
clang: error: clang frontend command failed with exit code 70 (use -v to see
