Thanks for the vote of confidence!

It might be helpful if you could send us that log file.

There's no way that should happen -- unless there's some nasty 
equivocation going on over the size in bytes of some relevant 
types, such as "integer" (long int) or double, which is of course 
possible on a 64-bit system.

Are you sure the lapack libraries are not broken?  One possibility 
would be to write a little test program for lapack and see if it 
runs/crashes.

You can get CVS gretl at 
http://sourceforge.net/cvs/?group_id=36234

However, I'm not aware of any recent changes to gretl_matrix.c 
that would make any difference in this regard.

Any users of gretl on 64-bit machines out there with wisdom to 
contribute?
