Hi,

just seen in the builds due FORTIFY of the glibc:

/home/abuild/rpmbuild/BUILD/n
curses-5.9/ncurses/../progs/tic xterm linux vt100 vt102
creating temporary terminfo directory...
infocmp: sorting by terminfo name order
infocmp: width = 60, tversion = 0, outform = 0
infocmp: reading entry xterm from file 
/home/abuild/rpmbuild/BUILD/ncurses-5.9/ncurses/tmp_info/x/xterm
*** buffer overflow detected ***: infocmp terminated
