Crash when prefetch is used

[Asd-g]

In AvsPmod when I hit F5 (sometimes once, sometimes several times) r3950 is crashing (r3944 is fine). Script to reproduce:

ColorBars(640, 480, "YV12")
for (i = 0, 100)
{
Expr(last, "x x + x x + +")

Prefetch(2)
}

Increasing the prefetch number makes the crash more often.

Thanks, I see it, theoretically this should never happen (I put there an assert as well), I love such issues :)

Thanks.
