Hex Memory Addresses: Reading Pointers and Stack Traces in Hex When a program crashes or you attach a debugger, you're confronted with hex memory addresses: , , . These aren't opaque noise — they tell you exactly where in memory something happened, what region of the address space you're in, and often what went wrong. This article teaches you to read memory addresses, understand the address space layout, and interpret stack traces and crash dumps. --- Why Memory Addresses Are Shown in Hex A 64-bit memory address is a 64-bit integer. As decimal, would be — 15 digits that tell you nothing. As hex, it's 12 characters that encode the exact byte-level layout: Each hex digit is 4 bits. 16 hex digits = 64 bits = one full 64-bit address. Two hex digits = one byte. The alignment and region are…
