Yup. mips64-linux, specifically.

Build glibc for n32 or n64, using the patch for glibc 2.3.1 I posted
to the glibc mailing list a while back. Not even ld.so works. I
haven't gone as far as creating a small testcase for it, but I
remember it did trigger the conditions I listed.

Understood. Well, I can only wish you good luck and hope you succeed
where I failed. I wasted only 1 or 2 days on this, so perhaps being
smarter and/or having more time, you can succeed. I hope the pointers
to the locations where I remember having found problems help.
Still, if you could post the patch here, I'm sure it could help those
who want just a stop-gap solution for branches to global symbols
within the same section, while the full-fledged solution is still
being worked on.
