--- Comment #43 from David Edelsohn <dje at gcc dot gnu.org> --- I tried RC2 and it again failed. I configured again with your configure command and what appears to be your build command, and it succeeded. One difference is my normal bootstrap script still use the contrib/gcc_build shell script, which invokes "make -jX bootstrap". I am testing if the "bootstrap" target specifically elicits the comparison failure.
