Hi All, I'm a newbie to boost and have a storng interest in the graph algorithms in boost. I tried to run both kolmogorov and edmund-karp examples and got many warnings due to deprecated conversions in the read_dimacs function When I tried to run these examples I got segmentation faults. Other simple program (from boost homepage) that I tried to compile and run, run well. Is there any known issue about using boost with gcc 4 and later? Thanks, Moti -- __ Moti Freiman, Ph.D Student.
