ICE extern(C++) static

[TurkeyMan]

Another ICE

1>d\ud\pointcloud\pointcloudformat.d(112): Error: variable x ICE: C++ static non- __gshared non-extern variables not supported
1>Assertion failed: 0, file D:\OpenSource\ldc\ldc-release\dmd2\cppmangle.c, line 298

Given:

extern(C++):
 static immutable(int)[4] x;

What's strange is, there are reasonable error messages being emitted... but the compiler still asserts and pops up a crash dialog.

This is an upstream/frontend problem. The mangler emits the error message and then dies:

    if (!(d->storage_class & (STCextern | STCgshared)))
    {
        d->error("Internal Compiler Error: C++ static non- __gshared non-extern variables not supported");
        assert(0);
    }

Perhaps it's the implementation of d->error() is different for LDC?
I seem to get a lot of errors in crash/ICE pop-up dialog boxes from LDC, and modal dialog boxes in windows interrupt the build process. I have never seen the same thing from DMD, and not with the exact same code as I've been reporting here.

[yebblies]

It's not ->error(), it's the assert that comes right after it. These ICEs are because these types are not handled by the C++ mangler, and they should have already been rejected during semantic.

[dnadlinger]

These errors do not crash the compiler any longer. To actually add support for further parts of C++, the changes should go into the upstream frontend first.

Yep, no crash, no dialog box anymore, just a regular error.
