Also, all C's will SOMETIMES not do what you expect or want and being able to look at the assembler code they (should) produce and understand what it is (or isn't) doing is a big bonus. Some would say it is essential. When a compiler goes wrong you are completely stuck if you can't work out why it does what it does.

Another issue here is that very often you can see in the assembler what is wrong with the way you wrote a complex c statement. The advantage of knowing assembler while coding C is not limited to catching bugs in the compiler, it is also useful to catch bugs buzzing around in your head.
