Back in the day I used to consult for Sony Ericsson. We had like 5000 engineers writing C code that ran as a single executable in a single address space(!). Memory corruption was rampant. So rampant in fact that when we finally got an MMU it took months before we could turn it on in release builds, because there were so many memory corruption bugs even in the released product. The software just wouldn’t work unless it could overwrite memory here and there.
