Como localizar parte do código que cria a região mapeada de memória privada Anônima

Question

Estou analisando /proc/pid/smaps output para o processo C ++ e localizo um grande número de regiões mapeadas de memória privada. O número de regiões mapeadas na memória continua crescendo com base no tráfego.

Existe uma maneira de rastrear qual parte do código cria blocos de memória? Eu tentei strace -p <pid> , mas não consegui chegar à pilha enquanto ela é criada.
