That's assuming that heisenbugs are caused by concurrent programming alone. But a ton of heisenbugs happen in boring single-threaded programs.

Any programming language with pointers such as C or c++ where you can have wild pointers, use after free etc can be a breeding ground or hisenbugs. Consider yourself lucky.
