Regression in rewriter

[Machiry]

Consider the following code:

#define	ulong	unsigned long

ulong *		TOP;
ulong			channelColumns;

void
DescribeChannel(void)
{
    ulong	col;
    TOP = (ulong *)malloc((channelColumns+1) * sizeof(ulong));
    TOP[col] = 0;
}

When you run with alltypes:
./cconv-standalone -alltypes <foo.c>, you get the following:

#define	ulong	unsigned long

_Array_ptr<unsigned long> TOP = ((void * TOP)0);
ulong			channelColumns;

void
DescribeChannel(void)
{
    ulong	col;
    TOP = (_Array_ptr<unsigned long> )malloc((channelColumns+1) * sizeof(ulong));
    TOP[col] = 0;
}

See the invalid cast:

_Array_ptr<unsigned long> TOP = ((void * TOP)0);

This has to be:

_Array_ptr<unsigned long> TOP = ((void *)0);

Some issue with the latest DeclRewriter refactoring.

I think this is much older. See b960a3b at the latest, but I think it goes back farther.
