The operation for example h = sqrt(2); does not work at runtime. In general it's hard to debug. The cc should test if a variable is declared or not. Regards, grepi Reproducible: Always Steps to Reproduce: 1.h = sqrt(2); without declaration of h 2.h = sqrt(2); without declaration of h 3.h = sqrt(2); without declaration of h Actual Results: no compiler warning/error on not declared and used variables Expected Results: compiler warning/error on not declared and used variables -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
