Arch Linux

Description:

clang-3.1-1 does not seem to have been built/packaged with the address sanitizer (http://clang.llvm.org/docs/AddressSanitizer.html) libraries. These are useful for finding memory related bugs.

Additional info:
* package version(s)
clang-3.1-1
llvm-3.1-1

* config and/or log files etc.
None.

Steps to reproduce:
How to build a simple binary to check for asan-support:
[bo@archawesome asan-build (master) Wed 08:58 ]$ cat test.cpp
#include <iostream>

int main(int argc, char **argv)
{
#if defined(__has_feature) && __has_feature(address_sanitizer)
std::cout << "We have asan support." << std::endl;
#else
std::cout << "We do not have asan support." << std::endl;
#endif
return 0;
}
[bo@archawesome asan-build (master) Wed 09:02 ]$ clang++ -O2 -faddress-sanitizer test.cpp -o foo
