[REBOL] **Crash (Should not happen)
From: larry::ecotope::com at: 8-May-2001 20:21
Hi all,
I was trying to explore the ctx-edit object in View 1.1 on Win98. View was
started by booting direct to the console with no user code in user.r. Here
is the annotated console session.
-------------------------------------------------
>> edit-ob: context ctx-edit
>> print mold edit-ob
** Script Error: Not enough memory
** Near: print mold edit-ob
>> rebol/stats
== 8559840
>> recycle
>> rebol/stats
== 3456224
>> b: third edit-ob
; Console cursor disappears, interpreter seems hung.
; I changed focus to another app window. Then there
; was a bell sound and a hilite dialog in the task-bar
; (only on Win98) with this title and msg:
REBOL - Fatal System Error
**Crash (Should not happen) - Corrupt datatype: 96
; Clicking back in the console, I was still able
; to cut and paste the following
== ** Script Error: Not enough memory
** Near:
--------------------------------------------------------
In prior sessions, I established that with ctx-viewtop loaded into an
object:
print mold ctx-viewtop
and
print mold ctx-viewtop/dtc-face
both lead to the out-of-memory error above when REBOL has used about 16.3 MB
of Windows memory. rebol/stats shows about 11 Mb after the out-of-memory
error. Recycle puts stats back to about 4 MB.
I also found that
b: third ctx-viewtop/dtc-face
resulted in the same Fatal System Error as above.
An important observation is that
>>print mold system/view
works ok. So there is something special about the way that ctx-viewtop and
ctx-edit are written that causes important system functions like MOLD and
THIRD to fail. I looked at ctx-edit because it is a small object.
It is also true that
>>print mold system
worked in the later View betas without producing an out-of-memory error. As
far as I can tell, the only parts of View 1.1 which produce the
out-of-memory error are ctx-viewtop and ctx-edit, because if you boot to the
console with these still in the form of spec blocks
>>print mold system
works just fine.
