Dear boost developers,
You can find a new version of my portable precise C++ garbage collector in vault/memory.
Is any one interested? How does this collector determine the location of pointers on the stack and within the heap?
An internal bit map is used as a pointer database. Each bit represents one pointer location in memory. When the class gc_ptr<T> is created, the bit that corresponds to the pointer's address is set. When a pointer is destroyed, the same bit is reset. The bitmap is organized in pages of 4K and allocated dynamically. The collector sweeps unused pages at collection time.
