Luck, in this case bad luck. What happens when you access memory though an uninitialized pointer depends on what value the pointer gets. You may find that running the (buggy) program under ddd several times produces differing results. gcc's -Wall command line option may help find uninitialized pointers. Hopefully someone more knowledgeable will chime in. make clean make CFLAGS=-Wall will recompile everything with more warnings. For even more warnings: make CFLAGS="-Wall -Wextra" ____________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/>
