Description of problem: ssh -X <ppc64host> # xclock (or firefox or any gui) with FC5 stock kernel: 2.6.15-1.2054_FC5 all is OK. # yum update and reboot with new 2.6.18-1.2200.fc5 kernel and repeat, but apps crash. Version-Release number of selected component (if applicable): FC5 yum update to latest How reproducible:easy Actual results: gui apps crash Expected results: success Additional info: I really did search for a duplicate but could not find any hits for kernel version & libc.so.6 :-) *** buffer overflow detected ***: xclock terminated ======= Backtrace: ========= /lib/libc.so.6(__chk_fail+0x68)[0xf6c4728] /lib/libc.so.6(__vsprintf_chk+0x0)[0xf6c38a0] /lib/libc.so.6(_IO_default_xsputn+0xf0)[0xf63a360] /lib/libc.so.6(_IO_vfprintf+0x14ac)[0xf60c97c] /lib/libc.so.6(__vsprintf_chk+0xc0)[0xf6c3960] /lib/libc.so.6(__sprintf_chk+0x68)[0xf6c3878] /usr/lib/libfontconfig.so.1[0xfded094] I believe other symptoms are vnc sessions coming up blank (with color, not black, but no desktop)

arrgg, please reject this copy as duplicate. Bugzilla told me (erroneously) that product = Fedora%20Core was invalid and I needed to retry. sorry.
