be careful with clang, sometimes is missing point,
your problem is coming not from this @"Arial Bold",
give the complete stack and explain what is the condition of the leak
False/positive: I have an extensive use of perf tools since years and
I didn't see that since a while
the leak can be deeper than your app === give the complete stack-trace
