> I thought this was fixed in 1.8.7
> Could you verify which branches (1.8.8, 1.8.7, 1.8.6) still show this problem?

I just ran the same tests on 1.8.6 and 1.8.7.  It's still not fixed.  I'm not sure where the source code for 1.8.8 is so I didn't test it.

The build information and test results are below.  I didn't test 1.8.7 with --disable-ucontext because that configure flag doesn't seem to exist anymore.

Admittedly, ruby 1.8.7 is much faster than 1.8.6, but 1.8.7 still has this bug.

I would be happy to test 1.8.8 if you would tell me where to get the source code.
