Take a look at the ELF spec.
This is no proof as many things that have been created as joined work

The following example caused gas to generate error and eventually segfault. I
could reproduce this on ppc and x86. arm works ok.

The original ELF spec was indeed created by these players. But, the design
allowed for a great deal of extensibility. All of the UN*X's have

You did respond twice to the same message, I didn't. :-)
Anyway, we all seem to agree that Sun doesn't "own" ELF.

Hi all,
[ sorry for crossposting ]
I have investigated a little bit GNU ld problems on Solaris related to
filter symbols and I seem to have identified one test case which fails
under all circumstances. I'd like to get some advices on how to best
proceed next.

If you want the syms left undefined, this first hack I'd try is
writing an add_symbol_hook that caused these syms to be ignored.
