This adds alpha.core.StoreToImmutable, a new alpha checker that detects writes to immutable memory regions, implementing part of SEI CERT Rule ENV30-C. The original proposal only handled global const variables, but this implementation extends it to also detect writes to: - Local const variables - String literals - Const parameters and struct members - Const arrays and pointers to const data This checker is the continuation of the work started by zukatsinadze.

// In C++14 and before, when initializing a lambda, the statement given in the checkBind callback is not the whole DeclExpr, but the CXXConstructExpr of the lambda object.
|
|
// FIXME: Once the API of checkBind provides more information about the statement, the checker should be simplified, and this test case will no longer be a cornercase in the checker.
