We should be detecting things like this as of D66325
<https://reviews.llvm.org/D66325> and D66423 <https://reviews.llvm.org/D66423>
(we remember which casts were successful and don't re-assume them again), but
`LocalizationChecker.cpp` turned out to have a false positive of this kind.
@Charusso, you may want to take a look.
================
Comment at: clang/lib/StaticAnalyzer/Checkers/LocalizationChecker.cpp:885-888
- const Decl *D = Call.getDecl();
- if (D && isa<FunctionDecl>(D)) {
- const FunctionDecl *FD = dyn_cast<FunctionDecl>(D);
- auto formals = FD->parameters();
----------------
Note: this was a false positive.
