C++ UNWIND EXCEPTION METADATA: A HIDDEN REVERSE ENGINEERING BONANZA
Summary from the TLDR InfoSec newsletter
This blog post discusses how C++ compilers insert wind and unwind metadata to ensure proper destructor calls during exceptions in C++ programs. Compilers invisibly insert special blocks to handle object destruction when exceptions occur, even if control flow skips normal destructor calls. Wind metadata provides valuable information for analyzing constructors and destructor calls in C++ programs.
