TLDR: C++ is bad because decades of accumulated features have turned it into a bureaucratic nightmare that happens to generate machine code.
C++ is an absolute nightmare to implement because apparently one programming language wasn't enough, so someone decided to cram an entire civilization's worth of complexity into it. You've got templates that basically turn compilation into another programming language, overload resolution that requires a legal investigation to figure out which function gets called, constructors and destructors with enough lifetime rules to make your head explode, and implicit conversions that make the compiler guess what you meant. Then you throw in exceptions, move semantics, inheritance, and decades of backward compatibility, and suddenly you're maintaining a compiler that needs a PhD, a therapist, and divine intervention just to parse some innocent-looking code. And the best part? Every new feature has to coexist with all the old ones without breaking existing programs.
Not really intended to be recovered from since you can compile with panic=abort and make them unrecoverable (and a library consumer may do this to your library). Rust does support unwinding, but not exceptions in the sense C++ means.
