Yeah, I managed to get access to a solaris-2.8 machine, even though I
wasn't able to bootstrap with Solaris as/ld (see below), I was able to
reproduce the failure. Re-checking on x86-linux-gnu revealed that it even
doesn't fix the problem there, so I must have mixed something up yesterday.
Frankly, I'm a bit at a loss here, cause I've tried several strategies
yesterday and they either didn't fix the testcase or caused some of the
weak tests to fail. Especially I tried to use the TREE_USED flag of the
WEAK_DECLS TREE_LIST to mark when a weak already had been assembled, but it
didn't work out :-(. I seem to misunderstand something about how the tree
structures are handled.
The bootstrap failure with solaris-2.8 as/ld and configured with:
This results in:
