I have been attempting to get a recent release of nethack working with X support, but have been having problems with it failing. The program does not core dump but instead reports some internal error which I was unable to locate and then exits. A copy of the program made before the failure has a _different checksum_ (using cksum) than the version that now will not work. The file sizes are the same but the contents differ somehow. In an attempt to stop the program from being corrupted I removed all write access to the file (chmod -w nethack) but the binary has still become corrupt from time to time. The binary does not automatically become corrupt, Only on occasion does the binary become corrupt. I was under the impression this was a problem with the filesystem but am not certain.
