R help - Jul 2005 - Library mclust in 64bit compiled R

Hi, All;

I tried to use library mclust in 64-bit compiled R 2.0.1 but failed.
Installation went smoothly without any warning or error. However, when I
tried to use them with the following simple code, it crashed.

Library(mclust)
Dat <- c(rnorm(20, mean=0, sd=0.2), rnorm(30, mean=1, sd=0.2))
Ind <- Mclust(dat, 1, 5)$classification
cbind(Dat, Ind)

The error message was:

/usr/local/R-2.0.1_64bit/lib/R/bin/BATCH: line 55: 18097 Done
( echo "invisible(options(echo = TRUE))"; cat ${in}; echo
"proc.time()" )
     18099 Segmentation fault      | ${R_HOME}/bin/R ${opts} >${out}
2>&1

Can anybody help me with this?
Thanks in advance,

Tae-Hoon Chung

you mean   "package  mclust"
{a package is installed in a library full of packages}

My desktop has been a 64-bit (AMD Athlon 64) for more than a
year now, and I do note small differences to 32-bit some times,
and even have found (and not yet solved) quite severe problem
with the akima package.

Not with 'mclust' though.
I've just run several 1000 of Mclust() fits like the one above
and not seen any problem.

- Does *every* call to Mclust() give a segmentation fault?

- I assume you -- or someone in your group has compiled this R version
from source.  Did you (or he/she) run  "make check" after
building from source?  Could you (or ..) asks to run it?

- What output do you get when you run 
  
  R -d gdb
  r

  then the above R code,
  and then maybe type 'bt' (backtrace) ?
