Implementation

Demonstrate heap profiling with Valgrind Massif.

Requirements:

Create program with various allocation patterns
Include intentional memory leaks for demonstration
Include high-watermark allocations (freed later)
Use malloc/free and show allocation lifetimes
Print allocation and deallocation events
Show different memory leak scenarios
Include temporary allocations (freed quickly)
Include long-lived allocations
Provide instructions for running massif
Analyze massif output and explain findings

Why This Matters

Massif's peak-vs-final heap comparison is the same technique engineers used to track down real memory leaks in long-running daemons like nginx workers and database connection poolers, where a slow leak only becomes visible after days of uptime, not in a quick test run. Reading a massif snapshot's call-stack attribution is a directly transferable skill to AddressSanitizer's leak reports and Heaptrack, the tools teams actually reach for in production incident response.
