+A library providing malloc debugging via VM protection

devel/ElectricFence/pkg/DESCR

@@ -0,0 +1,7 @@
+Electric Fence is a different kind of malloc() debugger. It uses the virtual
+memory hardware of your system to detect when software overruns the boundaries
+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.
