All crash output from terminal

I wrote a simple program make a query of "select * from Win32_Directory" to
WMI, and it crashes every time. But it works well on XP.
  And I find that it's caused by the funtion of seed_dirs(), in
dlls/wbemprox/builtin.c at line 1086, without checking if "const struct expr
*cond" is NULL. So when it's NULL code "cond->u.expr.left" would lead to the
crash.
  I found it on version 1.6 at first, and then downloaded v1.7 to install and
the problem still exists.
