--- Comment #7 from Jeffrey A. Law <law at redhat dot com> ---
202296 doesn't change anything WRT sequencing of operations; it merely allows
the threader to dive a bit deeper into the CFG to determine a final target for
a jump threading opportunity.
Presumably David bootstrapped the trunk, then built k3d? If so, then it might
be a mis-compilation of GCC itself. As I mentioned in c#3 I'm looking at one
of those right now.
If this failure occurs in a stage1 cc1plus, then, well, that's totally
different (and much easier to track down).
Either way, it's mine.
