This is the default behavior in Xlib.
If you wish to "fail softly," you can install your own X error
handler:
fl_initialize( &argc, argv, ... )
[...]
XSetErrorHandler( X_lose );
[...]
static int X_lose( Display *display, XErrorEvent *error_event )
{
/* Install your failure handler here */
}
There is also an IO Error Handler which is installed in a similar
manner. Refer to your favorite Xlib manual for further details.
[I generally force a core dump in the error handler just so I can get
a traceback to my offending function call. The core dump is, of
course, only really useful if the program is running in sync mode.]
