Hello all,

 

I am encountering trouble with lme4 on a 64-bit linux system, and I'm
wondering if any of you might have advice on how to circumvent it. Using
recent versions of lme4 and R, I was able to compile and install the
package, and use it with success on relatively small problems.  However,
when I tried to scale up to work on a big problem, applying lmer() with
thousands of observations and a hundred or so random effects, my R fails
reporting a segmentation fault.  I don't see the same problem on a
different 32-bit Mac OSX system, which runs the same code without
evident difficulty.

 

Some details of the setup where the problem occurs.  We've tried a few
combinations of things, so I write what we tried first, with variants
noted in parentheses:

 

Red Hat Enterprise Linux 4 (version 5)

R version 2.7.1 (2.6.1)

gcc/g++ compilers for C and C++, Portland Group Fortran compilers
(gcc/g++/gfortran, ie full GNU compiler suite) 

Matrix package version 0.999375-10  (installed with and without
--with-package-versions flag)

lme4 version 0.999375-16 (installed with and without
--with-package-versions flag)

 

Any suggestions?  I'd be very appreciative.

 

Ben
