Hi!

I get the error

>>>>>>>>>>
Beta execution aborted: Access violation.

Call chain: (nti_ms)

  item <PutText#>puttext# in ~beta/basiclib/private/betaenvbody
  item PutText#<puttext#> in ~beta/basiclib/betaenv
  item putline#<putline#> in ~beta/basiclib/betaenv
  comp <PROGRAM-~> in H:/development/arraytest

  basic component in ~beta/basiclib/betaenv
<<<<<<<<<<

when executing the following program:

>>>>>>>>>>
ORIGIN '~beta/basiclib/betaenv';
-- program: descriptor --

(#

	array1:[0]@
	(#
		i:@integer;
		t:^text;
		b:@boolean;
	#);

	array2:[0]@
	(#
		h:^text;
		j:@integer;
	#);

	do

	5->array1.new;

	1->array1[1].i;
	'Text1'->array1[1].t[];
	true->array1[1].b;

	2->array1[1].i;
	'Text2'->array1[1].t[];
	false->array1[1].b;

	3->array1[1].i;
	'Text3'->array1[1].t[];
	true->array1[1].b;

	4->array1[1].i;
	'Text4'->array1[1].t[];
	false->array1[1].b;

	5->array1[1].i;
	'Text5'->array1[1].t[];
	true->array1[1].b;

	array1->array2;

	(for i:array2.range repeat
		array2[i].h[]->putLine;
		array2[i].j->putInt;
		newLine;
	for);

	'Ready.'->putLine;
#)
<<<<<<<<<<

Well, the question is why it is allowed to use "array1->array2"?
The arrays differ in length and have different types of objects - why
can I do that?
Why doesn't the compiler abort?
