ICE when using Dictionary's each #8
Description
I am playing around with rust-core-foundation and encountered an ICE when using the dictionary's "each" iteration. The following snippet (part of an unsafe block) illustrates the issue:
let dicPtr: _c_void = CFArrayGetValueAtIndex(arrRef, i as CFIndex);
let dicRef: CFDictionaryRef = cast::transmute::<_c_void, CFDictionaryRef>(dicPtr);
io::println(fmt!("Dic count: %?", CFDictionaryGetCount(dicRef))); // works fine!let dic: CFDictionary<CFStringRef,CFTypeRef> = CFDictionary::wrap_owned(dicRef);
for dic.each |key, val| { // internal compiler error: unknown tag found in side tables: 5e}
This results in the following ICE:
error: internal compiler error: unknown tag found in side tables: 5e
rust: task failed at 'explicit failure', /Volumes/Users/xxx/rust/rust/src/libsyntax/diagnostic.rs:93
rust: task failed at 'explicit failure', /Volumes/Users/xxx/rust/rust/src/librustc/rustc.rc:353
rust: domain main @0x7fc96180ba10 root task failed
I realise that this issue is more related to the Rust compiler than this wrapper, but my Rust knowledge is insufficient to pinpoint the problem any closer than this.
EDIT: I was able to reduce the problem to the following code:
extern mod core_foundation;
use core_foundation::base::{CFTypeRef};
use core_foundation::string::{CFStringRef};
use core_foundation::dictionary::{CFDictionary};
fn main() {
let _dic = CFDictionary::new::<CFStringRef, CFTypeRef>([]);
}
