profiler-memory-start

profiler-memory-start is a built-in function in `C source code'.

(profiler-memory-start)

Start/restart the memory profiler.
The memory profiler will take samples of the call-stack whenever a new
allocation takes place. Note that most small allocations only trigger
the profiler occasionally.
