Every mnemonic directly maps to binary bytes parsed by processor decoders. When high-level logic overflows memory, machine instructions faithfully copy bytes right over return pointers.

Read authored assembly registers and buffer-smash snapshots

Read the explanation

This workbench selects authored instruction and register snapshots; it does not compile or execute C. Its buffer-smash preset declares a four-byte buffer and assigns twelve as the displayed payload byte count. Bars use forty pixels per byte, showing one hundred sixty pixels for capacity and four hundred eighty for payload. The recorded strcpy smash step marks saved return and frame records corrupt. Treat the trace as its authored illustration, not a tested exploit or an actual process memory dump. The written debug trace starts its stack pointer at hexadecimal seven F F F five F B C, then subtracts hexadecimal ten, sixteen decimal bytes, to seven F F F five F A C for local stack space. Pushing a pointer argument later subtracts another four bytes. Both bars show changes in allocated bytes at thirty pixels per byte: sixteen for the local allocation and four for that push. Preserve the exact source registers independently of this change-in-bytes view. It describes this authored trace, not every x86 compiler ABI. Before the smash call the displayed stack entries are all marked not corrupted. At its seventh authored step four of the five displayed records carry corrupted true, including return, frame, buffer and padding. Bars show zero versus four marked records at one hundred twenty pixels per record. Flags here are prewritten state data, not dynamic detection or proof that a runtime sanitizer ran. Optimization buttons select separate authored configurations; inspect each whole exported opcode and register trace.
