Ok, I did some digging, and it turns out that this is another regression, completely unrelated to this problem. Awesome work Kenji !

Slightly verified test case.
1. Remove UFCS in order to compile the code by using old compiler.
2. Add dummy return type 'int' to parsePrimaryExpression function.
Compilation succeeds until 2.059. but with 2.060 and later, it causes cannot
access frame of function error.
auto lex(R)(R ) {
struct Lexer {
int t;
@property
auto front() { return t; }
}
auto lexer = Lexer();
return lexer;
}
auto flattenMixin() {
auto trange = lex('\0');
parsePrimaryExpression(trange);
}
int parsePrimaryExpression(R)(R trange) {
parseAmbiguous!(/*delegate*/(parsed) {
trange.front;
})(trange);
return 1;
}
typeof(handler(null)) parseAmbiguous(alias handler, R)(R trange) {
return handler(parsePrimaryExpression(trange));
}
void main() {}

http://d.puremagic.com/issues/show_bug.cgi?id=11220 --- Comment #2 from deadalnix deadal...@gmail.com 2013-10-10 18:32:06 PDT --- This is surprising because I'm working with 2.063.2 . I guess I'm somehow being lucky. It may be dependant on the compilation order or the way things are spread accross modules. Anyway, this is quite a showstopper. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

Even smaller test case:
struct Lexer {
int x;
}
int parsePrimaryExpression(Lexer trange) {
parseAmbiguous!( (parsed){ trange.x += 1; } )(trange);
return 1;
}
typeof(handler(null)) parseAmbiguous(alias handler)(Lexer trange) {
return handler(parsePrimaryExpression(trange));
}

And smaller still:
int parsePrimaryExpression(int x) {
parseAmbiguous!( (parsed){ x += 1; } )();
return 1;
}
typeof(handler(1)) parseAmbiguous(alias handler)() {
return handler(parsePrimaryExpression(1));
}

http://d.puremagic.com/issues/show_bug.cgi?id=11220 --- Comment #5 from Walter Bright bugzi...@digitalmars.com 2013-10-10 20:41:53 PDT --- The trouble is in the typeof(handler(1)). The type is void, but the compiler instantiates the template handler along the way, and handler needs a frame pointer, and doesn't have one, hence the error. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

If I write it this way:
int parsePrimaryExpression(int x) {
parseAmbiguous!( (parsed){ x += 1; } )();
return 1;
}
template parseAmbiguous(alias handler)
{
typeof(handler(1))
//void
parseAmbiguous() {
return handler(1);
}
}
We can see that instantiating handler(1) outside the function parseAmbiguous()
is what causes the error, because it needs the frame of parseAmbiguous().
