1 Electric Fence is a debugger that uses virtual memory hardware to detect illegal
2 memory accesses.
3 It can detect two common programming bugs:
4 software that overruns or underruns the boundaries of a malloc() memory allocation,
5 and software that touches a memory allocation that has been released by free().
7 Unlike other malloc() debuggers, Electric Fence will detect read accesses as well
8 as writes, and it will stop and pinpoint the exact instruction that causes an error.
9 It is not as thorough as Purify, however.
11 In order to debug a program it needs to be linked with Electric Fence's library or
12 dynamic linking needs to be used.
