Electric Fence, Utilities, Electric Fence 2.1 Electric Fence is a different kind of malloc() debugger. It uses the virtual memory hardware of your system to detect when software overruns the boundary of a malloc() buffer. It will also detect any accesses of memory that has been released by free(). Because it uses the VM hardware for detection, Electric Fence stops your program on the first instruction that causes a bounds violation. It's then trivial to use a debugger to display the offending statement. The archive EFENCE.ZIP contains the source code for Electric Fence 2.1. GNV is required to build Electric Fence on OpenVMS. The latest version of GNV can be downloaded from the link below. http://h71000.www7.hp.com/opensource/gnv.html To Build Electric Fence 2.1 on OpenVMS: 1. Unpack the EFENCE.ZIP zip archive under GNV 2. Go to the "efence" subdirectory and run "make"
