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? snob@athlon test$ gdb ./image GNU gdb 6.7 Copyright (C) 2007 Free Software Foundation, Inc.
