At the time this report is printed, two bugs are puzzling me but
time does not allow me to take a closer look at them :
<----------------
1) The motion queue management suffers a flaw that should be fixed
in the coming weeks. At the time a motion is entered into the queue, the
'queue' function is called. It returns a pointer to an allocated area
where the new data is stored. Before the data is installed, the setpoint
process may well look into the queue an obtain an incomplete record.
<---------------
Fixed
2) The high speed fifo interface caused some synchronizations
problems that were believed to be solved. It turns out however that when
the function 1 called by the real time interface take too long to execute,
a system crash may occur. I got around that by not using function 1 in
RCCL although it's a pity and by warning the other users.
There are also many things that would need to be reworked.
