Exploring Modern Debugger Capabilities for Memory Tracing and Analysis
By

Slow-proofed and worth the wait. Worth its weight in flour.
Summary
The article discusses the need for a modern equivalent to the DDD debugger, exploring how contemporary debuggers could improve memory debugging capabilities. It suggests that while tracking heap allocations and global variables is relatively straightforward, the real challenge lies in tracing memory obtained from the stack. The content proposes that debuggers could trace allocator API returns to establish data lifetime starting points, then monitor access to those addresses while gathering high-level information about readers and writers.

Global variables should also be trivial (fairly so) as you'll just need to track memory accesses to their address.
This doesn't sound like a particularly difficult problem for some scenarios.
Of course, further work is required to actually apply
