[Nauty-list] malfunction of listg

[Susanne Nieß]

There is something curious going on with listg. I used it to bring 
several big files that geng had made into a human readable format. When 
I tried this on a 32 bit system (Solaris), the biggest input files all 
gave output files of identical size, some of them ending in the middle 
of a graph. When I tried it on a 64-bit system (Linux) to avoid this, I 
did get files of different sizes, but the sizes of the outfiles were in 
no way proportional to the sizes of the infiles. There was no error 
message. What is happening here and what can I do to get sensible output?
