Well, Dwarf2 debugging info may still contain misaligned references
(and forever they will; that's just the way Dwarf2 debugging info is),
so I don't see how the compiler might avoid emitting references that
would trigger the assembler/linker bug.  Do you have any indication
that this is no longer the case?

I do have access to a Solaris 2.6 machine, and, indeed, I can't
reproduce the problem you had reported using GCC 2.95.  However, this
doesn't mean much.  It may well be the case that whatever work-around
is in place because of LINKER_DOES_NOT_WORK_WITH_DWARF2 is doing its
job and avoiding the problem.  Unfortunately, I no longer have gcc
2.8.* on this machine to compare the assembly input that triggered the
problem with the one I get now.
