I've seen Qt Creator segfault due to the CMake plugin doing some strange QStringList operations on an inconsistent "implicitly shared" collection, that I guess broke due to multithreading (though I'm not sure exactly what happened). In RSS Guard, performing two different "background sync" operations causes two different threads to touch the same list collections, producing a segfault. (These are due to multiple threads touching the same collection/pointers; racing on primitive values is probably less directly going to lead to memory unsafety.)

Apparently in Golang, you can achieve memory unsafety through data races: https://blog.stalkr.net/2015/04/golang-data-races-to-break-m... (though I'm not sure if a workaround has been added to prevent memory unsafety).
