But that's a very serious type of bug because it means you have
situations where a program fails and you can't debug it

This is just not true.

Sorry for the noise, looks like my snapshot tarball build from git repo using
git-archive has some problems as the gcc-4.3-20071123 snapshot bootstrap

I am trying to bootstrap gcc with the following config :

Not quite. There were codeless gimple constructs before (think
labels, for one). Or empty asm statements.

This snapshot has been generated from the GCC 4.3 SVN branch

I appreciate your reply, Joe.
But I do not think this is off-topic, though. If we are going to discuss
the details of your project, Ptolomy, right, then it would have been
off-topic, I think. But I'm talking about GCC, therefore I believe this
is the right place to post these ideas.
