That sounds like you do not have the same processor in both systems and the processor on the 2nd system is not the same architecture as the -march= with which the program was compiled. eg if you compiled on a P4 and used -march=pentium4 then tried running the program on a Pentium. -- [EMAIL PROTECTED] mailing list
