[lttng-dev] Valgrind Memory Error in lttng-relayd

[Aravind HT]

Hi,

I ran valgrind on lttng-relayd for a soft hang issue that I had reported
earlier.
http://lists.lttng.org/pipermail/lttng-dev/2015-May/024533.html

Below are the list of errors that I found.

==793== Thread 4:
==793== Invalid write of size 8

==793==    by 0x5ED8AFC: clone (clone.S:111)
==793==

Are there any known bugs/fixes for these ?
