matlab mex function under 64-bit linux- panic |

Octave-3.0.0
I am using a 64 linux machine with the SuiteSparse set of routines.
I would like to use some of the mex functions that are defined within
SuiteSparse-
and are not directly callable from octave.
I have managed to make a small test on a 32 bit machine and compile the LDL
routines
mkoctfile --mex -I../Include -I../../UFconfig -DLDL_LONG -o ldlsparse.mex
.../Source/ldl.c ldlmex.c
mkoctfile --mex -I../Include -I../../UFconfig -DLDL_LONG -o ldlsymbol.mex
.../Source/ldl.c ldlsymbolmex.c
The result works when I add the directory path into octave.
****************************
When I try the same thing on a 64 bit machine I have the following problem
>path('/opt/SuiteSparse2/LDL/MATLAB',path);
>M=speye(10);
>ldlsparse(M);
I obtain
panic: Segmentation fault -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Segmentation fault
****************************
Is the mex interface "aimed" at 64 bit machines"
or is it only 32 bit?
