I have a quick question. What does the following runtime error mean? *** glibc detected *** free(): invalid next size (fast): 0x0804a1c0 *** Does this mean that the program attempted to free memory from a pointer that wasn't allocated any memory? I have a feeling that is what this means, but the message itself is cryptic. On a related note, does anyone know of a good source that describes runtime errors such as this in detail? It would help me greatly in my debugging experience. Thanks :) James -- My blog: http://www.crazydrclaw.com/ My homepage: http://james.colannino.org/
