instrumentation framework for dynamic analysis tools
Valgrind is an instrumentation framework for building dynamic analysis
tools. There are Valgrind tools that can automatically detect many memory
management and threading bugs, and profile your programs in detail. You
can also use Valgrind to build new tools.

This OpenBSD port is still very preliminary and has minimal functionality
(memcheck).  All problems should be reported to the "valgrind-openbsd" page:
