There are two noreturn functions in the X server: FatalError and AbortServer. Having any of those two functions in the middle of a call stack will prevent unwinding the program properly and stops the backtrace at those functions in gdb. The file containing FatalError and AbortServer, os/log.c, has to be compiled with the -mapcs-frame option on ARM to get proper backtraces. Automake imposes its own restrictions on compiling individual source files with different options. The recommended way to do this is to put os/log.c into a convenience library and add this library inside os/libos.la. See the documentation of GNU Automake manual, version 1.11.1, section 27.8 Per-Object Flags Emulation, for details.

X Server The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into. Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders. For a comprehensive overview of X Server and X Window System, consult the following article: http://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: http://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver http://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: http://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: http://wiki.x.org/wiki/GitPage
