immutable(ReflectionInfo)* reflection;

struct ReflectionInfo
{
	const(ReflectionInfo)[] objects;
}

$ gdb --args dmd -g test.d
Comment 1 Trass3r 2011-11-29 13:03:59 UTC 
Another interesting testcase:

class ApiProvider
{
	void _getCsrfInfo() {} // comment this out and it suddenly works
	immutable(ReflectionInfo)* reflection;
}

struct ReflectionInfo
{
	const(ReflectionInfo)[] objects;
}
