In the windows implementation you check lengths, viz., MAX_PROFILE_LENGTH etc. 
Here you accept the system profile length.  How come?  Does
CGColorSpaceCopyICCProfile vet the profile somehow?  Is it trustworthy?

Done.

+    const unsigned char* sys_profile = CFDataGetBytePtr(icc_profile);
+    profile->assign(sys_profile, sys_profile + length);
+  }
