Abstract
A method of detecting and indicating pointers in an ephemeral region of memory in a computing system includes monitoring stored memory for pointers; detecting if there are pointers above the ephemeral range; and if there are not pointers above the ephemeral range, then testing if a pointer is above a lower limit of the ephemeral range without testing if the pointer is also below an upper limit of the ephemeral range. A system for detecting and indicating pointers in an ephemeral region of memory in a computing system includes a monitor module, a pointer module, and a lower limit module. The monitor module monitors stored memory for pointers. The pointer module detects if there are pointers above the ephemeral range. The lower limit module tests if a pointer is above a lower limit of the ephemeral range without testing if the pointer is also below an upper limit of the ephemeral range, if there are not pointers above the ephemeral range.
