Yep, this is definitely annoying. I just hadn't pestered Walter about it yet.
Thx for the bug! :P

Comment 4 bearophile_hugs 2013-06-27 13:04:53 UTC 
Also take a look at the test cases in Issue 10450 

Another test case:

import core.simd: double2;
struct Foo {
    double2 x;
    this(uint) {
        x = [0.0, 0.0];
    }
}
void main() {
    Foo y = Foo();
}



dmd gives the same error with -g:

Internal error: backend\cgcv.c 2162


ldmd2 gives even without -g:

fpext source and destination must both be a vector or neither
  %tmp1 = fpext double 0x7FFC000000000000 to <2 x double>
Broken module found, compilation aborted!

Comment 7 Martin Nowak 2013-11-30 12:43:24 UTC 
The test case also fails on linux (see bug 11655).
Comment 8 Rainer Schuetze 2013-11-30 23:58:53 UTC 
The failure of the test case in comment 4 is not related to generating debug info. It is covered by issue 11655, so I think we can close this one.
