           Summary: Crash on inferring function literal return type with
                    undefined identifier
           Product: D

            Status: NEW
          Keywords: ice-on-invalid-code
          Severity: normal
          Priority: P3
         Component: DMD

Either of the following pieces of code causes a crash - no internal error
message, a downright "dmd.exe has encountered a problem".

(I'm tagging this as "ice-on-invalid-code" even though there's no ICE, just a
crash.)

--
void main() {
        x = function(){};
}
--
void main() {
        y = 2;
        auto x = function(){};
}
--

The above examples can, of course, be extended: using any undefined identifier
at some point in the code and then, below that, trying to have a function
literal's return type inferred seems to cause this crash.

The error regarding the identifier is correctly reported prior to the crash, so
the problem can be found and fixed easily, and hence this isn't that bad even
though the compiler does crash.
