lookup message trying to write to a file

[juliatiupsam]

Dear all,
I get the following message:

lookup 0x08048000 0x00000358 -> 0xb7e74000 0x000560c0 /1 fwrite

executing:

FILE * data_file = fopen("patterns.ptt", "w");
if(data_file!=NULL){
char ppt[] ="patterns:";
fwrite(ppt,sizeof(char),strlen(ppt),data_file);
...
fclose(data_file);
}
The same message is thrown using any of these other functions:
fputc('\n',data_file);

fputs("inputs:\t",data_file);

fprintf(1,"%d",inputs);

Does anyone know the reason?
Thanks in advance,

Yes, you have an error somewhere in the code you have not shown us.
Please provide a small, complete, compilable example program that
exhibits the problem.

You need to pass data_file as the first argument to fprintf(). However the
rest of the code looks fine. There is some sort of internal error in the
file system. Try a new name and a different physical drive.

This looks like some kind of debugging message from the dynamic loader
on a Linux system. Unfortunately, all one can say is that there's
probably an error somewhere in your code that is causing it to be
printed. If you can post a short *complete* program that provokes the
error, we may be able to help you.
