Thanks for looking into this. I'm chasing a more urgent bug this weekend,
so may not get around to another test for a day or two.

With my upload bandwidth it would be very impractical, sorry.
How about I share my scripts I use to checkout, configure and build?

Should I try building trunk in ThinLTO mode using 3.9? I mean, is trunk
considered stable enough for building and later use as occasional
CC/CXX? I might try the build regardles, just to check...
