--- Comment #6 from Mikael Pettersson <mikpe at it dot uu.se> 2011-09-25 15:25:01 UTC --- According to my bisection, the bug started on trunk for 4.5.0 with r147851, stopped on trunk for 4.6.0 with r164136, and stopped on 4.5 branch with r175813. I can't say if those fixes are proper or just masking a latent issue.
