With g++ is there a runtime setting to scramble freed memory with delete?

Does anyone know how I can for the g++ or gcc runtime to scramble the ram where an object was after delete? I have a theory that I'm using an 开发者_StackOverflow社区object after it has been deleted but in practice it rarely crashes.

I'd suggesting running with valgrind - that'll tell you if you're accessing memory after freeing it.

inline void operator delete(void* memblock) { //you custom stuff } would override the global. I used to use this for security so that we could zero out the memory so its less likely to leak important information.

You can overload delete for your object if you like.
