But the kvt has a buffer overflow. If the size of the new title of the window is big enough then the kvt will do a core dump.xterm too (version 3.3.2.3) coredumps... I tried this with echo -e "\033]2;(60e+06 times 'a')\007"
Tried the same with xterm 3.3.3 on i586, 64M RAM, 128M swap, continuously increasing the number of 'a's (perl -e 'print "a" x 60000', 600000, 600000...). But instead of xterm crash got Fvwm2 hangup after 6e6 "a"s. I.e. everything else works -- I ould even press the "play" button in x11amp with mouse, except Fvwm2. "strace -p <fvwm2pid>" shows that Fvwm2 waits infinitely on select(). The only choice was to kill the window manager. All progs are from stock RedHat 6.0/i386 -- "Fvwm Version 2.2 compiled on Apr 9 1999 at 16:15:38". ___________________________________________________________________ Dmitry Yu.
