+<p>As unbelievable as it may sound, Clang does crash from time to time.  
+Generally, this only occurs to those living on the 
+<a href="http://llvm.org/releases/download.html#svn">bleeding edge</a>.  Clang
+goes to great lengths to assist you in filing a bug report.  Specifically, Clang
+generates preprocessed source file(s) and associated run script(s) upon a
+crash.  These files should be attached to a bug report to ease reproducibility
+of the failure.  Below are the command line options to control the crash
+diagnostics.
+</p>
+
+<p><b>-fno-crash-diagnostics</b>: Disable auto-generation of preprocessed 
+source files during a clang crash.</p>
+
+<p>The -fno-crash-diagnostics flag can be helpful for speeding the process of
+generating a delta reduced test case.</p>
