This is Electric Fence 2.0 ALPHA 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 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.

This version is for SGI IRIX 5.0 . It's known to port to SunOS 4.1.2 with
a few type changes. It will probably port to any ANSI/POSIX system that
provides mmap(), /dev/zero, and mprotect(), as long as mprotect() has the
capability to turn off all access to a memory page.

The software license and complete information on its use is in the man
page: libefence.3, or libefence.cat for those of you who don't have troff.
