Dear Qingfen,
As a workaround, if you want really to keep gcc-4.8.1, you should
disable all strong optimizations (see gcc-4.8.2 changelogs, gcc-4.8.1
has problems with code optimization).
What you can do is the following: after the './configure gnu' command,
manually inspect the 'config.h' file in $AMBERHOME and replace all '-O3
-mtune=native' and '-O3' commands by '-O'. I tested it with gcc-4.8.1
and it works.
Gerald.
P.S.: However, I still suggest upgrading your compiler and/or your OS.
