Comment 1 Tom Hughes 2018-01-12 08:31:54 UTC 
This system call was enabled a year ago - please update to the latest release.
Comment 2 bugger 2018-01-12 10:28:31 UTC 
Thanks for your reply..
updated valgrind to 3.11.13 the latest release still it shows the same error...

Comment 3 Tom Hughes 2018-01-12 10:57:17 UTC 
No that's completely different - that's just valgrind doing it's job and telling you that your program is passing uninitialised data to a system call.
