Comment 1 Dominique d'Humieres 2013-05-30 15:43:22 UTC 
It looks similar to pr57467.
Comment 2 Dominique d'Humieres 2013-05-30 17:35:25 UTC 
Fails also on x86_64-apple-darwin10.
Comment 3 Hans-Peter Nilsson 2013-05-30 21:31:50 UTC 
Confirming; cris-elf too (r199421:199433], being an emutls target.
Comment 4 Hans-Peter Nilsson 2013-06-02 08:08:27 UTC 
Seems to have been fixed with the "Symtab cleanups 2/17 - merge alias code" fix (r199577) or possibly with the same fix as for PR57467 (r199582).

Fixed on arm-none-eabi it seems.
Dominique, can you confirm that x86_64-apple-darwin10 is fixed as well?
Comment 6 Rainer Orth 2013-06-03 12:30:27 UTC 
Also fails on Solaris 9 with Sun as, will check if current mainline works again.

Both i386-pc-solaris2.9 and sparc-sun-solaris2.9 bootstraps have now
completed and as of r199603, all emutls related failures are gone.

Thanks.
