Comment (by robstoon):
So it appears that 902-unaligned_access_hacks.patch, which nbd changed in
the last fix, does touch that ipv6_opt_accepted function. I'm not exactly
sure what difference the patch is doing to the code generation, but it's
clearly something, as the generated assembly in that function is different
with and without the patch on that file. From what I can see in the
disassembly, it appears the compiler may be reordering some of the checks
in the if statement in that function, which might be something to do with
why it's blowing up.
I'm currently testing a build with the hunk of the patch that touches
af_inet6.c removed to see if that fixes the crash.
