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
