BUG does not happen if I do not do "strace cinfo dtfile" with O_DIRECT
test file. It's easy to reproduce.
Without strace BUG does not happen.
Now I got it again, with also the mincore patch applied:
01:48:42.831060 mincore(0x37ff1000, 2147254272, ^[
2007-01-07 01:48:51.
147266560,
You rightly noted in a followup that there have been changes to
mincore, but I doubt they have any bearing on this: I think the
BUG just happened at the same time as your mincore.

Linux 2.6.19.1 SMP [2] on Pentium D...
I was running dt-15.14 [2] and I ran
"cinfo datafile" (it does mincore()).
Well it went OK but when I ran "strace cinfo datafile"...:
