--- Comment #3 from David Edelsohn <dje at gcc dot gnu.org> 2011-03-02 22:29:43 UTC --- I can reproduce this bug. It occurs in AIX 32 bit mode, but not in AIX 64 bit mode. Linux 32 bit mode ABI is different than AIX 32 bit ABI, so it is more difficult for LTC to reproduce. They are going to try Linux 32 bit -fpic/-fPIC.
