I only make it to the second phone interview.

In the first phone interview, I was asked to write a short program. In the second phone interview, he asked several questions about my resume.

Write a function to set a particular field of a register to the desired value.

For example, set bits 3-10 of a word to a given value.

Suppose the program you are running has a stack overflow. You want to know when and where this happens, but you don't want to use debuggers because they slow down the process. How would you do this?
