Nice calculation. Helpful to use to start countdown to April 22nd... I'm just kidding :) However, despite I reported this issue just few hours ago, it's since two or three days that I have been struggling with this issue. =20 =46inally I found the "culprit": the "Undefined Sanity Checker" (UBSan). I had enabled it some days ago and forgot about it. When I set it, I=20 (wrongly) thought that, since I have CONFIG_WERROR set to off, it wouldn't= =20 have failed the builds. I was just expecting error messages, my fault :( What led me to figure out this explanation are the messages I got. If you=20 noticed, they were all about "case label does not reduce to an integer=20 constant". Well, now I have some more stuff to fix in mainline for my spare time :) Thanks again, =46abio
