Summary: Cannot forward reference the typeof of the base type of
a pointer whose base type is defined with typeof
Product: D
Version: 1.014
Platform: PC
OS/Version: Windows
Status: NEW
Keywords: diagnostic, rejects-valid
Severity: normal
Priority: P3
Component: DMD
AssignedTo: bugzilla digitalmars.com
ReportedBy: deewiant gmail.com

nThis:
One of those hard to summarize legibly, yet relatively simple, bugs:
void f(typeof(*y) z) {}
typeof(x)* y;
int x;
Replace typeof(x) or typeof(*y) with int or move f after y and the code
compiles. As it is, it emits "Error: error: forward reference of typeof(x)"
without a line number for the error, in both DMD 1.014 and 1.015.

------- Comment #1 from deewiant gmail.com 2007-06-15 11:11 -------
I was going to file this as a separate Bug, but it seems it's just a wonky
error message for essentially the same thing:
void f(typeof(*y) z) {}
typeof(&x) y;
int x;
The above code errors out with the senseless "Error: can only * a pointer, not
a 'typeof(&x)'", but at least it comes with a line number pointing at the
typeof(*y), unlike the original code which used typeof(x)*.

------- Comment #2 from deewiant gmail.com 2007-06-15 11:16 -------
Further testing:
f isn't needed, "typeof(*y) z;" is enough.
However, in the original ("typeof(x)* y;") case, using only "typeof(*y) z;"
without f causes a compiler crash (no error message). Hence I'm stepping up the
severity.

This is no longer an ICE, just one of the many rejects-valid forward reference
issue.

Here's a patch, but I am not 100% sure, whether the scope is correct for the
type aswell.
Index: expression.c
===================================================================
--- expression.c (revision 421)
+++ expression.c (working copy)
-7432,6 +7432,7
error("can only * a pointer, not a '%s'", e1->type->toChars());
return new ErrorExp();
}
+ type = type->semantic(e1->loc, sc); // correct scope?
rvalue();
}
return this;
