...No more segfaults thus far but strangely the proper switch case...
One thing that I can think looking at your code:
import std.stdio;
void main(){
int op = 1;
switch(op){
default: writeln("default"); return;
version(XYZ){
case 1: writeln(op); break;
}
case 2: writeln(op);
}
}
Since XYZ is never set, case 1 will never hit and it will print
"default". if you comment or take "version(XYZ)" out there it
will work.
