| arch: x86_64
Xorg: 7.3, xorg-server: 1.4
gcc: 4.2.2
kernel: 2.6.23
glibc: 2.6.1
fltk: 5963
With default configure settings "test/image" application crashes Xorg session. I.e. X-Windows server segfaults.
When compiled with --enable-xshm, "test/image" don't crash Xorg but segfaults self. Probably there is some nasty bug in visual select?
