Sorry, Wrong Number: Debugging a Crash under Wine
Summary
The article provides a detailed, hands-on debugging walkthrough of a crash when running a Windows DLL under Wine, focusing on pseudo-relocations in MinGW, relocation semantics, and ASLR interactions. It documents the investigative process with GDB and rr, explains how a CALL to a non-mapped address can cause a crash, and discusses why Wine's ASLR handling differs from Windows, concluding that the issue lies in relocation/ASLR behavior rather than a Wine bug.
