Yes in most of the cases. You didn't explain what your program is doing, and how critical it is, and what is your computer hardware. The rare differences would be if your program depend (implicitly) on some buggy behavior of Glibc 2.12.0 which has been improved in Glibc 2.12.1 There could also be operating system differences. For example, if your program uses popen to run a program available on one computer, but not on the other. Or if your program fopen-s a file which is present on one computer and not on the other.
