BUG: Bad rss-counter state

[Markus Trippelsdorf]

I've hit the following warning after I've tried to link Firofox's libxul
with "-flto -lto-partition=none" on my machine with 8GB memory. I've
killed the process after it used all the memory and 90% of my swap
space. Before the machine was rebooted I saw these messages:

These warnings were introduced by c3f0327f8e9d7. Wouldn't it make sense to hide
them under some debugging option? AFAICS they contain no information that could
be of any use to a casual user.
