strange loss of accuracies under Win NT

Dear All,

It's been several times I observed a very strange behaviour with R 1.2.0
under Windows NT 4.0 (with sp5): accuracies are lost in many cases. Things
are back to normal when I exit R and restart it. Here is an example of my
last encounter with this:

bt1 <- c(7.3, 8.1, 8.4, 7, 6, 7.2, 6.7, 8.3, 9, 7.4, 8.6, 6.2, 6.9, 7.6,

5.3, 5.6)

bt1

[1] 7 8 8 7 6 7 6 8 9 7 8 6 6 7 5 5

1000*0.1

[1] 0

log(0.9999)

[1] -Inf

log(1.9999)

[1] 0

log(2)

[1] 0,6931472


I used R 1.1.1 on the same computer quite a lot, and never saw this. Has
anyone seen this with R 1.2.0?
