Is it possible to use an UDA to generate a struct inside a class ?

Yes, the compiler should never crash but produce an error message. 
Please report it preferably with a reduced code sample:

It has the same problem on git head.

         foreach(m; __traits(allMembers, tp)) {
             foreach(o; __traits(getOverloads, tp, m)) {
                 foreach(attr; __traits(getAttributes, o)) {
                     static if (is(attr == get)) {
                         writeln(attr.stringof, " < ", m);
                         alias PT = ReturnType!o;
                         //auto ICE = &o; //comment = no crash

You realize, all of those foreach'es are processed at compile-time for 
code generation. There will be no 'o' at run time; so its address cannot 
be used. The compiler problem is probably related to that.

                     } else if (is(attr == set)) {

You probably want that to be 'else static if'. Otherwise, when the 
previous 'static if' fails the condition, there will be an 'if' 
statement inserted, which would get executed at run time.

void main(string args[]){

Compiling with the -w compiler switch produces the following warning:

Warning: instead of C-style syntax, use D-style syntax 'string[] args'
