Test case:

void boo(T)(T* ptr, const ref T t)
{
    static if (__traits(compiles, ptr.__postblit()))
        {}
}

void main()
{
    double b;
    const double a = b;
    double* ptr;
    boo!double(ptr, a);
}

Commenting out static if (...) line makes it work. Or otherwise if you call boo
with non-const argument(b) it works too.

This one is a blocker for QtD. Basically I need the way, to allocate a copy of a value on the C heap. In order to do that I allocate the memory chunk with malloc, then call memcpy() and then, if the value type has postblit I call it. This bugs prevents me to implement this.

Oh sorry my wrong, it is not that a big blocker, but I believe it is worth investigating anyway, since the issue was hard to narrow down and cost me couple of hours of identifying.

Thanks.

This was fixed in DMD2.037.
