+Subject: [PATCH] Ensure duplinvolvedmap_all is reset when a solver is reused
+
+Otherwise, if solver is used with a SOLVER_DISTUPGRADE job, then reused
+without one, this will cause solver_addduprules() to be called, even
+though needduprules is 0, which will crash trying to dereference
+solv->dupmap, which is NULL because solver_createdupmaps() hasn't been
+called.
+
+Conflict:NA
