FIX: An access violation occurs on Cl.exe when you build a C++ class that contains thousands of members in Visual Studio 2008

In Microsoft Visual Studio 2008, you create a C++ class that contains thousands of members. When you build the source when the Debug Information Format option is turned on, a window appears that indicates that the Microsoft C/C++ Compiler Driver has stopped working. In addition, in the Error List window, you receive an error message that resembles the following:
Error result -1073741819 returned from '[InstallDrive]\Program Files\Microsoft Visual Studio 9.0\VC\bin\cl.exe'.
If you debug the problem, you see an exception that resembles the following:
Unhandled exception at 0x682a3841 in cl.exe: 0xC0000005: Access violation writing location 0x00210ffc.
  • The value "0x682a3841" may change at different times.
  • The problem occurs only when the number of members in the class is extremely large and exceeds the expected value for the compiler.
  • The Debug Information Format options include /Z7, /Zi, /ZI.
When the Debug Information Format option is turned on when you build the source, debug information is collected for the thousands of members. The data that is collected exceeds the limit of the internal buffer. This causes an internal compiler error.

To prevent this problem from occurring, delete the Debug Information Format option, add the /typedil- option, and then compile the project. However, the generated binary will not have the debug information.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
The C++ Standard recommends that compilers allow for at least 4,096 instance members and 1,024 static members for any one class. Additionally, the Visual C++ compiler can usually handle thousands more members than that. There is not a hard-coded limit for the number of instance class members or static class members. However, the amount of virtual memory will impose a practical limit on the compilation. When you use tools that generate C++ source code and then compile debug symbols for classes that exceed this limit, the size of a buffer that is used in the first compilation pass is exceeded. Then, an internal compiler error occurs.
