Shooting in the dark here (I can't reproduce the error for whatever reason), but for similar problems, I've found this fixes it:
Add a function somewhere in your file that says: void hackAroundBug() { writeln(typeid(int[string])); } You never actually need to call it. Just putting it there gives the compiler that extra nudge to put the symbol back into the object file. The error I saw was related to .rehash being missing, but it fixed it for me and might work here too. My older method was to add -I/home/me/d/dmd2/src/druntime/src /home/me/d/dmd2/src/druntime/src/object_.d -d On to the DMD command line (object_.d has the code needed for various AA things). Of course remember to fix the paths there to your dmd source. But with the referencing typeinfo workaround, I haven't needed to do this at all anymore.
