it to fail to reclaim discarded memory, leading to eventual collapse due to
|

memory exhaustion. Also (esp. at CMU) called
|

<a href="../C/core-leak.html"><i class="glossterm">core leak</i></a>. These problems were severe on older machines with small,
|
||
fixed-size address spaces, and special “<span class="quote">leak detection</span>” tools
|
||
were commonly written to root them out. With the advent of virtual memory,
|
||
it is unfortunately easier to be sloppy about wasting a bit of memory
|
||
(although when you run out of memory on a VM machine, it means you've got a
|

<span class="emphasis"><em>real</em></span> leak!). See <a href="../A/aliasing-bug.html"><i class="glossterm">aliasing bug</i></a>,
