The whole program run fine all the way down and does what its suposed to do up till where its suposed to exit then it crash to segmentation fault instead of exiting... but only on Ubuntu 9.10 not Gentoo which are the 2 distros i tested so far?!?!?!
From my experience, it usually means that your program has a bug, and that you were lucky enough on Gentoo that the bug doesn't appear. Chances are tiny that it is actually a ubuntu problem.

Did you tried to run your program under valgrind?

GEN_KEYMAP(1)						  Ubuntu General Commands Manual					     GEN_KEYMAP(1)

NAME
gen_keymap -- generate a keyboard map decision tree SYNOPSIS
gen_keymap list ... DESCRIPTION
gen_keymap generates a decision tree from a set of keyboard maps which can be used to help a user decide which keyboard map to use. The pro- gram using the decision tree typically asks the user to press some keys; at each step, it examines the returned keycode and uses it to prune the list of possible keyboard maps until there is only one left. OPTIONS
--version Show program's version number and exit. -?, --help Show help text. -v, --verbose Be more verbose. -mMINLEN, --minlen=MINLEN Too-short keymaps are skipped (default: 30 entries). -g, --graph Generate a hopefully-nice-looking .dot file. --maps Print the to-be-processed keymaps -i, --installer Input files are in d-i map form. -IDIRS, --inc=DIRS, --include=DIRS Add a directory to the search path. -oFILENAME, --output=FILENAME Set output file (default: stdout). -fFILTER, --filter=FILTER Include only the branches leading to these keymaps. -uUSEONLY, --useonly=USEONLY Start generating the tree based only on these keymaps. (The difference between --filter and --useonly is that the former generates the whole tree and then prunes it, while the latter only generates a reduced tree to begin with. This may have implications for perfor- mance on large trees.) -sSKIP, --skip=SKIP Keymaps to skip. -t, --test Test the generated maps. --interactive Ask user to choose among indistinguishable keymaps.
