Reproducible on sparc64-sun-solaris2.9 too.
Comment 3 David S. Miller 2003-07-19 00:34:29 UTC 
I checked in a fix written by Richard Henderson to both
the 3.3 branch and the mainline sources.

        * optabs.c (prepare_operand): Fail gracefully instead of abort
        if the predicate doesn't satisfy.
        (gen_cond_trap): Allow prepare_operand to fail.
        Pass correct opnum argument to prepare_operand.
