To see how many lines were executed in a small program:
(dbx) stop step -count infinity # step and stop when count=inf (2) stop step -count 0/infinity (dbx) run ... (dbx) status (2) stop step -count 133/infinity
The program never stops--the program terminates. 133 is the number of lines executed. This process is very slow though. This technique is more useful with breakpoints on functions that are called many times.
