I've just had ...
Assertion failure: 'type' on line 1493 in file 'expression.c'
any one know what this means ?

Generally, any time you see "assertion failure", it means that the
compiler is confused.  It probably means a bug.  Can you post the code
that caused the error (or, better yet, a tiny little source file that
does nothing but show the error)?

I've no idea where the error occured, the posted error message was all the D
compiler told me!
(kind of hopeing someone had seen this assert before).

posting source ... not really its within 648K of D source (full port to D of
win32 API headers winuser, winbase, commctrl)
the problem occured once I wrote wrapper class to win32 TreeView and might
be in there or inside my port of commcrtl.h (I do have my suspisions where
it lies .... )

I guess I'll have to start commenting code out until it builds.

Found the cause ....
its related to aliasing member functions ...

struct foo { }
alias foo * HMYFOO;

const HMYFOO FOO_ROOT  = ((HMYFOO)0xFFFF0000);

class fooTree
{
 HMYFOO getMyFooA( char[] str, HMYFOO item ) { return item; }
