--- Comment #3 from Richard Henderson <rth at gcc dot gnu.org> ---
I don't see this problem with mainline glibc, although I admit I
compiled for ev67, not ev4.  I just wouldn't have thought that
would make any difference.

$ ./elf/ld.so --library-path .:elf:math:nptl ~/a.out

Can you please re-verify mainline?  We're going to cut 2.20 soon.
