Bug 1697 – Internal error: ..\ztc\cgcod.c 2322 with -O

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;} }

> Removing any line of code in this example will make the error go away. 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); } } ----

Fixed in 1.026.
