Comment (by gk):
Current state of the art (comment:37:ticket:10599):
"
I uploaded a working build with ASan, UBSan and VTV to
https://people.torproject.org/~gk/testbuilds/asan/20140620/.
They are currently compiled with "-fvtable-verify=std". "-fvtable-
verify=preinit" does not work with ld but using gold seems to be fine.
I'll add that piece in the next iteration of these builds. In order to
avoid the browser exiting on VTV errors the compiler is built with
-DVTV_NO_ABORT.
