Hi Yao, Yes. As a work around i used dynamic linking to build and test the GDB.

Out of curiosity, how do you get a working gdb on AIX? Do you build gdb with libstdc++ and libgcc dynamic linking? I remember that GDB's exception handling on AIX is still broken if libstdc++ and libgcc is statically linked (which is the default).
