[cfe-commits] [PATCH] Disable source fortification on Darwin with AddressSanitizer

[Alexander Potapenko]

Hi all,

Because source fortification has been turned on in Xcode headers
recently, we have to disable it when building the code with
AddressSanitizer.
The proposed patch (see attached) defines _FORTIFY_SOURCE=0 if
-faddress-sanitizer is passed to the compiler.
Because other systems are not affected by the change, I've decided to
run the test only on Darwin (and introduced the 'system-darwin' config
feature)
