SYMPTOMS
When you use the Cl.exe compiler to compile source code, the Cl.exe compiler may stop responding. Additionally, you may experience high CPU usage. This problem occurs if one of the following conditions is true:
 * You enable the Generate XML Documentation Files property in the Microsoft Visual Studio 2005 development environment.
 * You use the Cl.exe compiler together with the /doc option.



CAUSE
This problem occurs because of a method declaration that does not specify all the parameter names. The following is a code example. void TestMethod(void* data1,void*/*data2*/); Note In the example, the following code is a comment.

/*data2*/

Therefore the second parameter of the type void* has no name.
