Description Maor 2015-06-02 10:54:06 UTC 
Created attachment 1525 [details]
a tar containing 2 tars (each with the code reproducing the bug on a specific dmd version)

Attached is the dustmite reduced code.

This bug reproduces on both dmd 2.066.1 & 2.067.1 (but the code reproducing it is slightly different, therefore, the attachment contains a tar with 2 tars in it , one for each version of dmd).

The reduced code has some compilation errors (the original one didn't) but the seg fault still happens.

after untarring the code just run:

for 2.066.1: dmd -g -w -c weka/XXX/XXZ/XXY.d -ofsome_obj.o
for 2.067.1: dmd -c weka/BXX/IXX/DXX.d

Comment 2 Kenji Hara 2015-06-03 10:34:47 UTC 
Reduced test case from the second tar for 2.067.1:

alias TypeTuple(T...) = T;

struct X
{
    static struct NA()
    {
        X x;

        void check()
        {
            x.func();
        }
    }

    alias na = NA!();

    auto func()
    {
        Y* p;
        p.func();
    }
}

struct Y
{
    mixin Mix;
}

template Mix()
{
    void func()
    {
        auto z = Z(null);
    }
}

struct Type(size_t v) {}

enum errVal = errorValue;

struct Z
{
    Type!errVal v;
}
