- Subject: Status of GCC memory checking, -fcheck-memory-usage
I've been spending the last few days looking for some kind of memory checker/debugger for use with GCC 3. I was completely suprised to NOT find any currently maintained checker with the kinds of features I'd like..
As I feel this is a major dificiency, and I currently have no interesting projects that I am working on, I would be willing to work on remedying this situation... so I have some questions:
1. Are there any memory debuggers that work with GCC that I am missing? Ive found memprof, mcheck, and some others.. but none are quite what GNU Checker used to be..
2. What is the status of -fcheck-memory usage in 3.0 and 2.96? What languages does it work with? I've poked around at it a bit, and it appears to be operational...
3. What is the status of GNU Checker? is this more-or-less officially a dead project at the moment?
4. How is this related to the -fbounds-checking i've been hearing about?
5. If I'm willing to write some code, what direction should I take? Are there any resources for doing this kind of thing?
>From what I can tell, -fcheck-memory-usage has tremendous possibilities.. not only access checking, but leak detection and memory/cache profiling .. it could be so exciting...
