Denys Petrov b30521c28a [analyzer] Wrong type cast occurs during pointer dereferencing after type punning
Summary: During pointer dereferencing CastRetrievedVal uses wrong type from the Store after type punning. Namely, the pointer casts to another type and then assigns with a value of one more another type. It produces NonLoc value when Loc is expected.

//===----------------------------------------------------------------------===//
// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:
