           Summary: Internal Compiler error  2322
           Product: D
           Version: 1.023
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: critical
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: dick221z yahoo.com


compiling the following with the switches "-O -inline -release" gives an
Internal error: ..\ztc\cgcod.c 2322

The error goes away if the -O switch is not used.
The problem 1st showed up in 1.023 and is also in 1.024.
Removing any line of code in this example will make the error go away.

-------------------------------------
import std.utf;
class foo1
{
        this(){}
        void method1( char [] name ){}
        void method2( int i, char [] name){}
}

struct foo
{
        char [] Name;
}


class someclass
{

    foo1 FooClass;      
    foo FooStruct;

    private:

    void func()
    {

        wchar [][] theNames;

        FooClass.method2(-1, FooStruct.Name);
        FooClass.method2(-1, FooStruct.Name);

        foreach( Name; theNames )
        {
            auto char [] thename  = toUTF8(Name);

            if( thename[0..3] == "123" )
                FooClass.method1(thename);

            if( thename[0..3] == "345" || thename[0..3] == "765" )           
                FooClass.method1(thename);           
        }

        FooClass.method2(-1, FooStruct.Name);      

    }

    public:
        this(){FooClass = new foo1;}

}

Simpler version follows. Sorry, I had to act on this statement. :-)

----
void f(int n) {}
void g(char[] s) {}

char[][] a;

class bar {
        int i;

        void func() {
                f(i);

                foreach (s; a) {
                        if (s == s){}
                        if (s[0..0] == "" && s[0..0])
                                g(s);
                }

                f(i);
        }
}
