Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |WORKSFORME --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Most likely asan is a static library which you specify before the object files so it is not used because of the linker defaults to an one pass linker. Also this is a binary release of the toolchain and GCC 4.9.x is no longer supported. Please file a support request to who you got the binary toolchain from.
