ICE when calling templated function from extern (C++) templated function?

[Elronnd via D.gnu]

Here's a minimal example:

  void r(T...)(T args) {}

  extern (C++) {
  void s(T...)(T args) { r(args); }
  }

  void main() {
  s(0);
  }

Traceback from GDC:

It seems the bug is also in dmd too?  Unless it is fixed in 
master/latest release, in which case will need to find out when 
this happened.


It works fine for me on dmd.

ICE with custom map template.

[Elronnd via D.gnu]

I get an ICE with the following code:


void main() {
import std.stdio;

template mmap(alias fun) {
void mmap(T...)(T list) {
foreach (item; list) {
fun(item);
}
}
}


void printstuffs(T...)(T args) {
void printer(G)(G arg) {
writeln(arg);
}

mmap!printer(args);
}


printstuffs("bla", 7, 9.0);
}


The message printed is:

test.d: In function ‘mmap’:
test.d:7:8: internal compiler error: in get_frame_for_symbol, at 
d/d-codegen.cc:2208

 fun(item);

ICE with static immutable RedBlackTree

[Elronnd via D.gnu]

There is this ICE:

void main() {
import std.container;
static immutable s = new RedBlackTree!int('h');
}

Hrmm.  I tried to create an account on the bugzilla, but got 
assaulted by this message:




 There was an error sending mail from

What's the situation with `static foreach` on gdc? When I 
install it using install.sh from 
https://dlang.org/install.html, I get 4.8.5, which does not 
support `static foreach`. That is also the version that is 
installed on travis-ci.org.


You can try compiling this version from source: 
https://github.com/moon-chilled/gdc-d2089


It is a WIP targeting gcc 10.  Didn't make it; I found it, and 
then it disappeared.  Once GCC 10 proper comes out, use that.
