Update (30-Sept-2016)

The Ubuntu build of gcc-6.2 ((Ubuntu 6.2.0-3ubuntu11~16.04) 6.2.0 20160901) no longer has this issue.

I'm using the Ubuntu build of gcc-6.1[1] ((Ubuntu 6.1.1-3ubuntu11~14.04.1) 6.1.1 20160511), GNU binutils 2.24, and libstdc++ with GLIBCXX_3.4.22 support. Even on a simple "hello world" program, specifying a sanitizer is not forcing use of the gold linker.

main.cpp

#include <iostream>
int main() {
    std::cout << "Hello, world!\n";
}

Compiling and linking

g++ -fsanitize=address -c -o main main.cpp
g++ -fsanitize=address -o main main.o

gives the error

/usr/bin/ld: unrecognized option '--push-state'
/usr/bin/ld: use the --help option for usage information
collect2: error: ld returned 1 exit status

Which indicates the -fsanitize option isn't selecting the gold linker. Of course, the simple fix is to use -fuse-ld=gold during linking, but previous builds of gcc didn't need this when using the sanitizers. For example, this code works perfectly fine under gcc-5.3 and 4.9 (both are Ubuntu builds). Is anyone else having this issue with non-Ubuntu builds of gcc-6.1? Are the Ubuntu builds broken?
