To freeze 1.4 on Win XP SP3, you can try this one out:
| tm border |
tm := TextMorph new.
tm contentsWrapped: '';
extent: 100 @ 20.
"this is the important stuff"
(border := AlignmentMorph newRow) position: 200 @ 200;
borderWidth: 1;
borderColor: Color black;
hResizing: #shrinkWrap;
vResizing: #shrinkWrap;
addMorph: tm.
"this just makes the TextMorph easier =to see"
World addMorph: border.
Then fill in the TextMorph with some text and newlines.
Then call the halos and resize the right corner for a while, especially
letting it go out of screen at the bottom.
The system will come unresponsive, not obey Cmd-. etc.
Sometimes it comes back to life but most of the time I've got to kill the
process.
CogVM or StackVM make no difference.
Maybe there is a huge GC going on but there is no memory display thing
(manuia) anymore in 1.4 so I can't tell.
Hope it helps.

Not sure if this is related but:
"The size is computed incorrectly."
TextMorph new
contents: (Text string: 'this is something longer than normal' attribute:
TextEmphasis italic);
fontName: #DejaVuSans size: 24;
openInHand.
doesn't computes the size right
