Hi Fabio,

It's a bug and I can repro it in both cases:

Steps to Reproduce:

1. Run following code

LOCAL ARRAY aSearch[1]
aSearch = ""
CREATE CURSOR myCursor (sMemo M)
APPEND BLANK	
GO BOTT
=ASCAN(aSearch,sMemo,1,0,0,1)	

2. Run following code and click on VFP desktop.

LOCAL ARRAY aSearch[1]
aSearch = ""
CREATE CURSOR myCursor (sMemo M)
APPEND BLANK	&& this is not necessary
=ASCAN(aSearch,sMemo,1,0,0,1)	

Observed Behavior:

VFP crashes in both cases

Expected Behavior:

No crash


>Run this code one or two times, and VFP go into a Crash exception.
