More suggestions: 

Make sure you are not writing past the end of allocated memory. How do 
you determine the length of the file? Are you sure the length you 
determined actually corresponds to the number of bytes you read in to the 
allocated buffer?

Make sure you included <stdlib.h>, and lose the cast to (char *) in your 
malloc line (assuming you are writing C).

Also, do consult the comp.lang.c FAQ.
