Original D1 case is patched here:
https://github.com/donc/dmd/commit/1acd2b64b10c4a985a10750d5ad83a0b7e98332b
Other cases patched for D2:
https://github.com/donc/dmd/commit/3a512771e31de4fb8b4e806154b08766fd97aed1
and for D1:
https://github.com/donc/dmd/commit/327afade5bfe0551176ee17ab6c991139dcb8058
Another test case from bug 5288:
auto bug4329e(int z) {
if (z) return undefined;
else return 0;
}
fixed here:
https://github.com/donc/dmd/commit/daff978816461602788f1cb396d9826918b6da21

One case:
void main() {
enum Foo { E }
Foo f;
switch (f) {
case 1: break;
default: break;
}
}
dmd 2.047 prints:
test.d(5): Error: cannot implicitly convert expression (1) of type int to Foo
test.d(5): Error: case must be a string or an integral constant, not __error

One case, dmd 2.047:

auto x = foo.bar!();
}
test.d(2): Error: undefined identifier foo

This is a case I have found:
void main() {
int[] a = cast(int[])array(iota(10));
}
dmd 2.047 prints:
temp.d(2): Error: undefined identifier array
temp.d(2): Error: undefined identifier iota
Error: cannot cast _error_ to int[]

TEST CASE D:
--
void bug4329d() {
make!(mess);

}
}
bug.d(37): Error: identifier 'mess' is not defined

Come on, fellas, you can do better than that. Here's 3 examples, and the last
one produces a segfault.
void bug4329()
{
with(great!().trepidation) return;
try{
throw CautionToTheWind;
} catch(LifeThreatening illness){}
}

Copied from bug 4335 for convenience:
---
import std.stdio;
void main() {
writeln("bug");
}
---
t.d(3): Error: 'writeln' is not defined, perhaps you need to import std.stdio;
?
t.d(3): Error: function expected before (), not __error of type _error_
(the first wrong error message is what bug 4335 is about)

They are only noise and don't add any additional > value. __error is a new improvement to the compiler to supress spurious error messages. (in previous releases, it would have been 'int'). You should never see them. Please post any test cases which produce them. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
