The output of the pmap -d command gives a output as follows.
sujith@linux-1xs7:~> pmap -d 7752

Why is pmap [heap] readings different from the actual program's heap memory usage?
I was learning how pmap analyzes the memory usage of a program. Running this very basic program that initializes an int array with 1,000,000 elements should theoretically use 4,000,000 bytes (I tried adding or removing stdlib.h, but I got the same…
