The same bug persists under Windows 7 and SBCL 1.2.14

[pipping (pipping)]

(sb-ext:run-program "ipconfig" '("/all") :output "foo" :search t)

gives me a file named "foo" with the right contents with sbcl 1.3.11 on windows server 2008. In other words: I can't reproduce this bug in that setting.

Whether this bug has been fixed in sbcl or continues to persist on XP/windows 7, I do not know.
