VS2012 Generation Code Slow with Large Hard Coded Arrays

Question

We have a tool that generates a class in a header file that is generated with hard-coded arrays. This autogenerated is inherited by a real implementation that uses auto-generated values.

Auto-generated example:

class MyTestAutoGen
{
    std::vector<int> m_my_parameter1;
    std::vector<int> m_my_parameter2;
    ...

public:
    MyTestAutoGen()    
    {
        SetDefaultValueFor_my_parameter1();
        SetDefaultValueFor_my_parameter2();
        ...
    }

    void SetDefaultValueFor_my_parameter1()
    {
        int tmp[] = {121,221,333,411,225,556,227,.......};
        m_my_parameter1.assign(tmp, tmp + 65025);
    }

    void SetDefaultValueFor_my_parameter2()
    {
        int tmp[] = {333,444,333,987,327,16728,227,.......};
        m_my_parameter2.assign(tmp, tmp + 65025);
    }

    ...
 };

Compilation takes a lot of time, and in the VS output windows I see that it hangs in the "Generating Code" phase of compilation, but it will complete compilation in about 15-30 minutes if the compiler does not work with a stack overflow.
