Summary:                    ncurses apps crash in _nc_read_entry(), Illegal
instruction on AMD K6-II
Description: 
Hi!

ncurses version is 5.5,REV=2006.02.10

All applications using ncurses (vim, gpg and probably many more) are
crashing here during startup on my AMD K6-II, possibly because of CPU
optimization:
