Judging by this line 
<https://github.com/llvm/llvm-project/blob/ebe408ad8003c946ef871b955ab18e64e82697cb/clang/lib/StaticAnalyzer/Core/BugReporterVisitors.cpp#L2730>
 in the `LikelyFalsePositiveSuppressionBRVisitor::finalizeVisitor()` method, it 
seems that the bug report is squelched when the visitor encounters an  
`ExplodedNode` which corresponds to a `LocationContext`, whose associated 
`Decl` lies in **std** namespace. I guess, by default, the option to suppress 
warnings from the std library is enabled. Which makes sense, except in this 
case since `unique_ptr` is in std and it is being used in that function, the 
bug report is suppressed.
