You are given a the source to a application which is crashing when run.
After running it 10 times in a debugger, you find it never crashes in the
same place. The application is single threaded, and uses only the C standard
library. What programming errors could be causing this crash? How would you
test each one? |

time related events are mostly in multi-threads
Mostly possible: variable non intialized, or invalid pointer. Also, in
debugger mod, variable in reg are mostly pushed into memory
