I have a program that compiles and runs fine under Win XP.
(using DevC++ beta 5).

I've compiled the same program under Linux (Debian Lenny) and Mac OS X 10.5.8.
(Using Eclipse). However when I try to run it from the command line I get this error:

terminate called after throwing an instance of 'std::out of range' what(): basic_string::s ubstr

When I try debugging from eclipse I get the error....
