R help - Jan 2005 - Segmentation fault while using Mclust function of mclust library in R-2.0.1

Hi, all;

I got an unusual error while using mclust library 2.1-7 on R 2.0.1.
When I tried to run Mclust(rnorm(100)), I got segmentation fault error.
Does anyone know what causes this problem?
I came across the same problem even when I tried to run the example shown in
Mclust help using iris data.

Thanks in advance,
Tae-Hoon Chung

Which OS? Have you (re)compiled the package yourself under R-2.0.1?
You might want to report a reproducible example (e.g. setting the seed 
in the example above) to the package maintainer, including the relevant 
information (including compiler and their versions).

Tae-Hoon,

Your code worked with version 1.90:
> Mclust(rnorm(100))
 best model: univariate normal with 1 groups

 averge/median classification uncertainty: 0 / 0 

Warning message: 
optimal number of clusters occurs at min choice in: Mclust
(rnorm(100)) 

The warning should be there because the data you generated 
have only one cluster.  I'm fairly certain it would work 
with R version 2.0 as well which is what I have on my home 
computer and I used Mclust for one-dimensional data last 
month with that version.  If it's a problem with the latest 
version, you can simply download an earlier version of R 
(yesterday there was a thread about where to find version 
1.91 or something like it) and run Mclust with that version.
