This reproduces the bug in about 15 minutes on my machine:

/* cc -o nop nop.c `pkg-config --cflags --libs x11` */
#include    <stdio.h>
#include    <stdint.h>
#include    <X11/Xlib.h>

int
main (int argc, char **argv)
{
	uint64_t	i = 0;
	Display *dpy = XOpenDisplay(NULL);

	for (;;) {
		++i;
		if ((i & 0xfffffff) == 0) {
			XFlush(dpy);
			printf ("0x%llx\n", i);
		}
		XNoOp(dpy);
	}
}
