Hi Corona,
Didn't work for me or did I do some mistakes? Here is the combined output for a sample program compilation:

I also ran strace over compilation and the strace log files are attached for your reference. Like:
Code:
[root@p208n11 tr]# strace g++34 cppProg.cpp -o trcpp2 2> strace.log
[root@p208n11 tr]# strace g++34 libstdc++.so cppProg.cpp -o trcpp2 2> strace.x.log

Also tried running ldconfig utility, like:
Code:
[root@p208n11 tr]# ldconfig -p > ldLib.log

Created a copy of file ldLib.log as ldLib.log.2 and edited the file ldLib.log.2 to swap positions of libstdc++.so.6 and libstdc++.so.5 and ran the config utility again, like:
Code:
[root@p208n11 tr]# ldconfig -f ldLib.log.2 2> ldconfig-f.log

Got errors logged into file ldconfig-f.log for reference and is attached herewith this post.

Here are few other information, which might be of help:
