-Subject: [PATCH] Prevent potential double-free in TNEFSubjectHandler
-
-If TNEFSubjectHandler is called multiple times, but the last time
-failed due to the PREALLOCCHECK, the subject.data member will be
-a freed, but invalid pointer. To prevent a double-free next time
-TNEFSubjectHandler is entered, set it to zero after freeing.
