Sorry, I should've mentioned them.
Just for the record: I cherry-picked your gnulib commit on top of
the currently used one in coreutils (4a829046).
This is on my native OpenSuSE-12.1 system - I did it 4 times
in a row to show the variance:
os121$ for f in $( seq 1000 ) ; do ./test-fdutimensat ; done 2>&1 | grep -v
Aborted
test-utimens.h:103: assertion failed
test-lutimens.h:64: assertion failed
test-utimens.h:130: assertion failed
test-utimens.h:130: assertion failed
os121$ for f in $( seq 1000 ) ; do ./test-fdutimensat ; done 2>&1 | grep -v
Aborted
test-utimens.h:119: assertion failed
os121$ for f in $( seq 1000 ) ; do ./test-fdutimensat ; done 2>&1 | grep -v
Aborted
test-utimens.h:103: assertion failed
test-utimens.h:103: assertion failed
test-futimens.h:57: assertion failed
test-utimens.h:103: assertion failed
os121$ for f in $( seq 1000 ) ; do ./test-fdutimensat ; done 2>&1 | grep -v
Aborted
test-utimens.h:103: assertion failed
test-utimens.h:117: assertion failed
test-utimens.h:103: assertion failed
test-utimens.h:103: assertion failed
test-utimens.h:130: assertion failed
test-lutimens.h:64: assertion failed
I.e., the numbers did not went significantly down for that non-VM system. ;-/
Attached is the output for the OpenSuSE-12.2-on-VirtualBox-on-Win7 test
(with the decrease of aborts about a third).
Finally, I repeated the test on a openSuSE-12.3 VM on Vmware Workstation,
also attached.
Have a nice day,
Berny
