failing test case

Using alloca in a function with a struct that has a destructor seems to cause
an internal compiler error in DMD. The following error message results:

Internal error: eh.c 54

A failing test case is attached.

For small test cases, please paste inline instead of attaching.

import core.stdc.stdlib;

struct TheStruct
{
    ~this()
    {
    }
}

void bar()
{
}

void main()
{
    auto s = TheStruct();
    bar();
    auto a = alloca(16);
}

I can't reproduce on win32, but that is not a surprise as eh.c is posix-only.
