I’ll reiterate, if it was a null pointer exception (I honestly don’t know that it was, but every comment I’ve made is based on that assumption, so let’s go with it for now) then I absolutely can blame C++, and the code author, and the code reviewer, and QA. Many links in the chain failed here. But C++ is not a memory safe language, and while it’s had mass improvements in that area in the last two decades, there are languages that make better guarantees about memory safety.
