Thanks for working on this issue. I just wanted to confirm Paolo's finding a segfault for
grep -Fif /dev/null < /dev/null for version 2.6.3. I confirmed this on i386. Also on x86_64 after recompiling pristine source with configure && make under gcc versions 4.3, 4.4, and current svn. Again, leaving out the -i switch produces no segfault in all cases. Moreover, Paulo, running any of this within a script makes no difference in my testing, as compared to just from the prompt. Bake
