$ gcc -Wall -o reversi reversi.c -DDEBUG=1 -save-temps reversi.c: In function 'alphabeta': reversi.c:376: warning: value computed is not used Expected behaviour: Loop prints 0....7 What happens: loop prints all 0's When I comment out the scanf call, 0....7 is printed as expected. I originally didn't use a second variable, but put it in out of desperation. The code compiles correctly with icc. There are no header files, the program is one self-contained C file. (If you are curious, it doesn't work.) -- Summary: A variable is reset for no apparent reason Product: gcc Version: 4.1.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jbarbero at cs dot washington dot edu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36304
