--- Comment #8 from Mikael Pettersson <mikpe at it dot uu.se> 2012-07-11 09:46:06 UTC --- Backporting r186159 and its followup fix r186164 to 4.7.1 was easy and fixed the test case there too (untested beyond this test case). Backporting those revisions to 4.6.3 required more elbow grease but didn't fix the test case there. I'm going to test the 4.7 backport properly now, in case a smaller more direct fix doesn't emerge soon.
