Here are other runs. The warmelt-normal-1.i is exactly the one uploaded in the bug report. Its md5sum is
944b6e0f8c6da76a7f0698e927fc4a60 warmelt-normal-1.i
And it does not seem to be some excess swapping. The cc1 process seems to eat half a gigabyte, and I have 8 gigabytes
(and mozilla, emacs, thunderbird don't eat all of them).
During a cc1

I checked on my wristwatch and the real timing is similar to the one reported by the computer (so its hardware clock is
apparently ok).
