I agree with what you’re saying even though I do think a lot of C++'s bad rep comes either from C or from pre-C++11 code. I also think that modern code should include clang-tidy in the CI, and if so at least simple mistakes like in OPs code would be flagged with “warning: Use of memory after it is freed [clang-analyzer-cplusplus.NewDelete]”
Note that all of the warnings in there are valid and should be fixed, so it’s not like wading through a see of false positives. That being said, the post is interesting in its explanation of why the example does what it does. Too bad all of the other stuff in there is bonkers.
Linters are good and should absolutely be used in any serious C++ project, but they can only catch the most basic sources of UB. I almost never make a mistake that a static analyzer can catch. It’s the multithreaded lifetime issues and data races that ambush you the hardest, and I don’t see any way a C++ static analyzer could hope to catch those.
But yes, most of the original post is bonkers and has the totally wrong conclusion.
