(split off from bug 5264)

module hrm;

struct BlkInfo { size_t size; }

extern (C) BlkInfo gc_qalloc();

void __setArrayAllocLength(ref BlkInfo info)
{
    if(info.size) {}
}

extern (C) void foo()
{
    BlkInfo info = gc_qalloc();
    __setArrayAllocLength(info);
}

$ dmd -m64 -c hrm.d Internal error: backend/cod1.c 2554

(same error and line number for both dmd1 and dmd2 from tip of svn for both)

call cleanup code in cod1.c funccall():

2936         if (tym1 == TYhfunc)
2937         {   // Hidden parameter is popped off by the callee
2938             c = genadjesp(c, -4);
2939             stackpush -= 4;

This code isn't aware of the 32 vs 64 bit calling convention differences yet?
