Note that llvm's cmake files show mach_override.c is compiled with -std=c99. # Custom flags: projects/compiler-rt/lib/interception/CMakeFiles/RTInterception.osx.dir/mach_override/mach_override.c.o_FLAGS = -std=c99 The interception/mach_override/mach_override.c.o object file will need to be linked into both libasan.dylib and libasan.a.
