From 3830186287fd83a1f6f0881287759f211184dd96 Mon Sep 17 00:00:00 2001 From: John Afaganis Date: Fri, 2 Jan 2026 22:16:41 -0700 Subject: [PATCH] Update unsigned long literals and format specifiers to work correctly in Windows (#3483) Previously, the code used unsigned long for literals and format specifiers to represent 64-bit unsigned values. While this worked on Linux, it caused compatibility issues on Windows. The C++ standard does not guarantee that long is 64 bits. On LP64 systems (e.g., Linux), long maps to 64-bit values, but on LLP64 systems (e.g., Windows), long maps to 32-bit values. This discrepancy led to incorrect behavior when assuming unsigned long was always 64-bit. This commit updates all relevant literals and format specifiers to explicitly use 64-bit unsigned types, ensuring consistent behavior across platforms.
