[comp.windows.x] GrabMatchesSecond bug?

ken@cwi.nl (Ken Yap) (12/24/87)

Has anybody seen this kind of server crash before? It happens very
rarely. When I had only a Whitechapel X11 server, I thought it
might be my ddx code or a compiler bug but but didn't have dbx to
investigate the problem.  Now I find it also happens with the
vanilla qvss server so I suspect a bug in dix. I have installed
all patches up to #93. I would compile with dbx to investigate but
it is X'mas eve and I'm hoping somebody knows exactly what is
happening and can tell me before I return in the new year. Many
thanks in advance.
