I've found 3 compiler bugs during my 15 years as professional developer. One was a optimizer bug sprintf in a for loop reset the ecx register so the loop became infinite and the last two where valid code that crashed the compiler (how do I know that, because the crashes dissappeared with small modifications of the code, like newlines). But yeah they are pretty rare.
