[Nauty-list] readgraph()

[Brendan McKay]

Hi, You can ignore the message
   warning: format not a string literal and no format arguments
as it does indicate an actual problem.

The warning occurs in situations like this:

int f(char *s)
{
    printf(s);
}

Some versions of the GCC compiler thinks it is suspicious, but it is
fine if the argument is an ordinary string, eg.  f("hello world\n").

The next release of nauty will avoid the warning by changing the
printf statement to printf("%s",s).

Brendan.

> Thank you very much, after moving the malloc() calls the code works. You are completely right, I accidently attached the wrong source code, sorry. The problem, however, occurred in both testnau4 and testnau3. On the unix machine where I testet them, both seemed to be in an endless loop until I killed them after 24 hours. I also tried it on a linux machine. The compiler made some warnings and the files it saved are different and both nonsense (no change between before and after moving the malloc) and I am still busy debugging that. When I installed the nauty package on linux, there were several warnings that I did not understand. Do they mean my system is somehow not compatible with nauty? I attach the file nautywarn2.txt with those warnings.
