Glibc 2.12.0 and 2.12.1 compatiblity

Hello,I have a short question: If I build something with glibc 2.12.1 (using crosstool-ng), will it work on computers which have glibc 2.12.0 installed?
I chechked the diff between the sources but I am not that knowledgeable about glibc so a more advisable opinion with be more helpful.
Thanks

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.
