ARM - after update from rtems4.9.3 to rtems-4.9.5 Unlimited Task Test fails



Hi all,

after updating from rtems-4.9.3 to rtems-4.9.5 the "Unlimited Task Test" on my
ARM cpu at91sam9263 fails with a message like...

which commonly means the cpu tries to access non available memory.

After removing the bugfix bug1718 the "Unlimited Task Test" works fine.

(https://www.rtems.org/bugzilla/show_bug.cgi?id=1718)

*** rtems-4.9.3: ./cpukit/sapi/include/confdefs.h *** unlimited task test works
[...skip...]

  #define CONFIGURE_MEMORY_PER_TASK_FOR_POSIX_API \
    _Configure_From_workspace( \
      sizeof (POSIX_API_Control) + \
     (sizeof (void *) * (CONFIGURE_MAXIMUM_POSIX_KEYS)) \
    )

*** rtems-4.9.5: ./cpukit/sapi/include/confdefs.h *** unlimited task test doesn't work
[...skip...]
  #define CONFIGURE_MEMORY_PER_TASK_FOR_POSIX_API \

    )

Any hints respectively does anyone observe the same?

Cheers
