miscompilation. Programs should be temporarily modified to disable outputs
that are likely to vary from run to run.
+* In the `crash debugger`_, ``bugpoint`` does not distiguish different crashes
+ during reduction. Thus, if new crash or miscompilation happens, ``bugpoint``
+ will continue with the new crash instead. If you would like to stick to
+ particular crash, you should write check scripts to validate the error

* In the code generator and miscompilation debuggers, debugging will go faster
if you manually modify the program or its inputs to reduce the runtime, but
still exhibit the problem.
