delegating constructors and "this = ..."

[jpf]

Hi,
I've come across some strange behavior using delegating constructors and
assignment to this. Please have a look a this testcase:
--------------------------------------
class Test
{
	static Test[void*] lookupTable;
	public int i = 0;
	
	public this (void* ptr)
	{
		//Check if there already is a D object for this ptr
		if(ptr in lookupTable)
		{
			this = lookupTable[ptr];
			assert(this.i == 15);	/* ok */
			return;
		}
		
		i = 15;
		lookupTable[ptr] = this;
	}
	
	public this (void* ptr, bool fake)
	{
		this(ptr);
		assert(this.i == 15);	/* fails */
	}
}

void main()
{
	int a,b; /*for different pointers*/
	
	Test test1 = new Test(&a);
	Test test2 = new Test(&a);
	
	Test test3 = new Test(&b, false);
	Test test4 = new Test(&b, false);
	
	assert(test1 is test2); /* ok */
	assert(test2.i == 15);	/* ok */
	assert(test3 is test4); /* fails */
	assert(test4.i == 15);	/* fails */
}
--------------------------------------
Tested with dmd 1.055. As soon as the constructors are delegated the
code doesn't work anymore. The assignment "this = lookupTable[ptr];"
still succeeds but in the "this(void* ptr, bool fake)" constructor the
this reference seems wrong. The returned object also isn't the one
assigned to "this".

I'm not sure if this is a bug, but it's at least unexpected behavior.
Should I file a bug for this issue? Would the correct bug-tracker for
this be http://d.puremagic.com/issues ?
