          Issue ID: 19735
           Summary: Error: variab extern symbols cannot have initializers
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: critical
          Priority: P1
         Component: dmd

Similar to issue 19734, but emphasis on the effect on user code, not the
blatant implementation bug.


Given the following example:

extern
{
    int f1(int a) { return a + 2; }

    int f2(int a) { int b = 42; return a + b; }
}

You get the error during compilation of f2:

Error: variable `b` extern symbols cannot have initializers

As has already been established in 19734, even the parameter `a` is considered
an extern symbol.  However, the function `f1` compiles and a body is emitted
without complaint.

Either `f1` should also be considered an error, or `f2` should be fixed to
become valid code.
