make aborts. Output log attached. This is highly reproducible - successive attempts to run make produce identical output (apart from a few addresses), except for one time that produced a StackOverflow.

• ruby -v changed from N/A - cannot build ruby, so cannot run "ruby -v" to miniruby 1.9.1p429 (2010-07-02 revision 28523) [i686-linux]

I would like to attempt a "git bisect" to find the problem using the git mirror. Is this reasonable? I see a tag for v_191_376 in the repository, but none for 378 patch (which is my current working ruby) or the broken 429 patch. Can you suggest commits that could use to begin a bisect? Or would it be better to use the subversion repository. Please advise.

=begin
Yes, it is reasonable.
You can use http://github.com/ruby/ruby/tree/ruby_1_9_1
previous patch release is http://github.com/ruby/ruby/commits/v1_9_1_378

This has been reported with issue #3243 as well, see also issue #2727.

I have attached the results of the git bisect.

Thanks for those pointers Juergen! I find that "optflags='-O1'" does not work on p249, but
"optflags='-O0'" and "optflags='-O2 -fno-inline'" do work.

Also, 1.9.2-rc1 does not have this problem.
