--- Comment #9 from Krishnamoorthy C <chandrakm at hotmail dot com> --- (In reply to Paolo Carlini from comment #8) > Something else besides AIX 7.1. Fore sure all the Linux targets are fine, > for example. This isn't a generic C++ front-end issue. The program works fine on all other OS's ( HP UX, Linux and WIndows ) except AIX 7.1 . Do you think using a lower gcc compiler version might help. thanks and regards, Krishna
