--- Comment #4 from Rainer Schuetze <r.sagitario at gmx.de> ---
Thanks. It's a builtin limitation of the recursive descend parser because the
if/else-series creates a deep tree of AST nodes. Even if optimized in the
parser the same problem will appear during analysis.

I will increase the stack size to 8 MB, similar to dmd. dmd also chokes at some
point, e.g.

module mod;

string genIfElse(int n)
{
        string s = "if(size_t.sizeof == 4) {}\n";
        foreach(i; 0..n)
                s ~= "else if(size_t.sizeof == 4) {}";
        return s;
}
void test()
{
        mixin(genIfElse(5000));
}
