This question is not appropriate for the mailing list gcc@gcc.gnu.org.
It would be appropriate for gcc-help@gcc.gnu.org.  Please take any
followups to gcc-help.  Thanks.

There are no intentional incompatibilities between these libraries.  If
you build a program with gcc 4.4.5, it should run correctly when using
the libstdc++ from gcc 4.5.1.  Of course there may be a bug.  It's hard
to say anything else without more information.
