https://bugs.freedesktop.org/show_bug.cgi?id=90887 --- Comment #12 from jr --- Thanks for pointing at the bug. I looked at it before filing this one. Cannot say now why I discarded it as a potential duplicate without testing the trace. You'd be less impressed if I told you how long it took:-) But I'm probably better at debugging old than writing new code. And it did help that I do have some experience with compilers even if that was decades ago (when SSA was a new thing). Unfortunately after I changed jobs 7 years ago I had to drop pretty much all my free software activities due to severe lack of energy. I do miss that time, though. Feel free to mail me, if you want me to look at something. -- You are receiving this mail because: You are the QA Contact for the bug. You are the assignee for the bug.
