The following will not compile, it give the followig error

   try
   {
    if ( c < 33 )

  }
  return o;

}

curiously removing the if ( c== 0) allows it to compile, and in this
example removing the if (o==null) does not but in the original code (which
was more complex) it did.

as an aside, commenting out the return does not give a 'this function has a
missing return value' but this error
: cannot goto forward into different try block level
as opposed to
: failToCompile function expected to return a value of type Object

only seems to occur in member functions. if its not a member function then
removing the return will result in it compiling without error.

I have to admit to being confused by the error message I assume it internal
exception stuff or have I totally missed the meaning of the error message.

This problem could be resolved so:

[dmd\src\phobos\object.d]
remove line: "extern (C) static int printf(char *, ...);"
add    line: "import c.stdio;"

Then everything works OK. =]

How do think?
