Programs with a data race can do all kinds of things that seem incredibly improbable to humans, because compilers assume that the program is race-free and make optimizations that are unsafe in the presence of races. See https://software.intel.com/en-us/blogs/2013/01/06/benign-data-races-what-could-possibly-go-wrong for a great writeup about this. It uses C++ for its examples, but the same ideas apply to Go.
