[Bug 1052] Seg Fault in realtime logging with several components

http://bugs.orocos.org/show_bug.cgi?id=1052

--- Comment #1 from Christian Fuchs <[email protected]> 2014-01-23 09:13:52 CET ---
The issue is caused by a race condition in the OCL::logging::Category's
OutputPort logging the last written message. 
The access to this variable is not threadsafe, leading to the old value being
free'd more than once, when two or more threads use the same category to log a
message concurrently.

A workaround is to set the OutputPort's default behaviour to not logging the
last written value.
