Does VA have a way to check for uninitialized variables in C++ code?

If you turn On the option:

VA Options -> Code Inspection -> Show Unevaluated Checkers

you can now filter the list of Code Inspection checkers with the string "uninitialized", which is bringing up 8 entries for me. Without looking up the details of how these work I am not sure how much they will help, but "Check for blocks that capture uninitialized values" sounds interesting. Unfortunately the documentation for this check is a little sparse:

https://clang.llvm.org/extra//clang-tidy/checks/clang-analyzer/core.uninitialized.CapturedBlockVariable.html

which is to say completely empty. So you will have to have a go and see how much help these checks are.

You may also want to make sure that the Code Inspection:

Find manually-defined constructor definitions that do not initialize all fields

is enabled since this will help.
