+==== Microsoft Specific Changes ====
+
+Dealing with the Invalid Parameter exception (0xc000000d):
+
+Starting with Visual Studio 2005, Microsoft re-vamped the whole C Runtime Library. Part of the re-vamp process was to do parameter checking on each function. Places that would normally return a NULL value now cause a structured exception to be thrown. 
+
+The nature of this structured exception is different than most as they specifically coded it so that it will not engage the BOINC Runtime Debugger and it'll display a dialog box asking the user if they wish to debug the error. If the user cancels the error code 0xc000000d is returned without any more information. 
+
+To get more information with this error you'll need to create a function like this: 
+{{{
+#ifdef _WIN32
+void AppInvalidParameterHandler(const wchar_t* expression, const wchar_t* function, const wchar_t* file, unsigned int line, uintptr_t pReserved ) {
+        fprintf(
+                stderr,
+                "Invalid parameter detected in function %s. File: %s Line: %d\n",
+                function,
+                file,
+                line
+        );
+        fprintf(
+                stderr,
+                "Expression: %s\n",
+                expression
+        );
+        // Cause a Debug Breakpoint.
+        DebugBreak();
+}
+#endif
+}}}
+
+The following code block should be added after the call to boinc_diagnostics_init(): 
+{{{
+#ifdef _WIN32
+        // Every once and awhile something looks at a std::vector or some other
+        // CRT/STL construct that throws an exception when an invalid parameter
+        // is detected.  In this case we should dump whatever information we 
+        // can and then bail.  When we bail we should dump as much data as 
+        // possible.
+        _set_invalid_parameter_handler(AppInvalidParameterHandler);
+#endif
+}}}
+
+When this issues happens in the future it'll describe which CRT function call was passed an invalid parameter and it should dump out the callstack for all threads. 
+
+The function blocks above overwrite the default behavior of the CRT when an invalid parameter is detected. 
+
