Segmentation Fault while loading format file

Hello,
I would bet that this error is a long term consequence of the error 
brought up by Andreas Hirsch 3 weeks ago: The latex.fmt files seem to be 
inconsistent across different platforms. So it might be necessary to 
keep different fmt-files, each one generated by the corresponding 
binary. (I have no idea, whether it is possible to individually 
configure the location of the proper fmt-file.) Maybe the simplest 
solution would be to have just one platform, say x86_64 on a machine. 
Are the linux systems that old, that you need to keep the i386 binaries?
Good luck
Alois
