+/*
+Hi,
+
+Im using SystemC 2.0b2 with gcc 2.95.3 (Linux). If I create an sc_lv 
+assignment with range methods on every side like
+
+lv1.range(15,8) = lv2.range(7,0);
+
+and the lv2 vector contains "z", I get the warning message
+
+WARNING: (E2004) sc_bv cannot contain values X and Z :
+ - ../../../../../src/sysc/datatypes/bit/sc_bv.h: 340
+
+and the assignment is not done. Further investigation revealed that the 
+vector seems to get mistakenly converted to a sc_bv in between. Removing the 
+range method on one side or adding a cast
+
+lv1.range(15,8) = (sc_lv<8>)lv2.range(7,0);
+
+solves that problem.
+
+Regards, S. Heithecker
