This says that the XWin process exited, so either gdb somehow failed to catch
it when it segfaulted.  Or did it not segfault at all?

So, this looks like maybe it's failing while trying to create a window, so
this might be a timing condition at startup.

You might try creating an empty ~/.startxwinrc (so the default xterm is not
started by startxwin) and see if that makes a difference?
