Comment (by alexcrichton):

 Ah unfortunately I don't think so in this situation. The problem is mostly
 with `cargo test` itself. Cargo alters `DYLD_LIBRARY_PATH` to include the
 rustc sysroot libdir which contains the ASan dylib, and I think because it
 has the same name as the system one it ends up trumping it (and then
 causing problems because it's different).

 Taking a look at Cargo it also looks like it prefixes DYLD_LIBRARY_PATH
 instead of suffixing it.

 Geez this really is a mess with Cargo and rustc! You can probably tell
 that many other projects probably haven't gotten ASan C code + Rust
 working yet...

 One of the better long-term fixes for this may be to rename rust's own
 copy of these dynamic libraries, ensuring that the don't clash with the
 system's perhaps
