5 MBX_Post from ISR failure - ID: 1459260

Last Update: Comment added ( fe64970103 )

Details:

Suppose the following situation. Task A was pending
(MBX_Post) on a mailbox and the mailbox was posted before
the timeout expired. Free space was given to the task
A. If an ISR happens which tries to post the mailbox in
question just after the CPU time was given to the task
A the system might failure.
