Custom Memory Heap Debugging

Acerca de

Provides specialized guidance for tackling one of C++ development's most difficult challenges: memory crashes that only manifest in release builds or during program shutdown. This skill offers a structured diagnostic workflow to identify subtle interactions between custom allocators, standard library internals, and static object lifetimes. It equips developers with practical strategies like forcing early library initialization and extending heap persistence to resolve use-after-free errors and segfaults that bypass traditional debugging methods and standard memory sanitizers.

Características Principales

• Strategies for forcing early standard library initialization to prevent allocator conflicts

Casos de Uso

• Investigating segfaults that occur only after main() returns during program shutdown
• Debugging memory corruption in optimized builds that does not appear in debug configurations
• Resolving conflicts between custom memory allocators and standard library components like locales or iostreams
