I am confused on the strategy here. Will the FSF gcc developers be
prohibiting
the addition of darwin support for libsanitizer until all issues in its
operation
are resolved? It seems like a chicken and egg situation. I think this should be
considered an experimental feature and exposed to as many developers as possible
so we can get some help on resolving these issues in mach_override.c. Making it
unnecessarily difficult to build this feature doesn't help with that project.
