Successful rtems_region_get_segment() returning NULL pointer ?

[Rolf Schroedter]

Found a workaround for the described problem:
With the following construct my application runs for several hours:

 > for(;;) {
 >     stat=rtems_region_get_segment(idRegion,size, \
 >                  RTEMS_NO_WAIT,RTEMS_NO_TIMEOUT,&ptr);
 >     if (stat == RTEMS_SUCCESSFUL) break;
 >     rtems_task_wake_after(10);
 > }

The following two constructs are occasionally stopping the task calling
rtems_region_return_segment() when the region is full.
 >     stat=rtems_region_get_segment(idRegion,size, \
 >                    RTEMS_WAIT,RTEMS_NO_TIMEOUT,&ptr);
or
 > for(;;) {
 >     stat=rtems_region_get_segment(idRegion,size,RTEMS_WAIT,10,&ptr);
 >     if (stat == RTEMS_SUCCESSFUL) break;
 > }

Really strange ...
I'm using RTEMS 4.6.0pre4, provided with the Leon-Sparc leccs1.2.2
development system.

Regards,
Rolf.
