#328 Assertion qxk:720 in QP/C/C++ 7.2.0

[Quantum Leaps]

While running QXK, assertion qxk:720 was observed in the following scenario:

• Extended thread with priority 6 calls schedLock with ceiling 7
• Priority 7 is basic thread
• Extended thread with priority 6 gets interrupted between QXK_schedLock & QXK_schedUnlock (priorities higher than 7 are running)
• Basic thread with priority 7 starts pending during the interruption
• Problem happens when higher priority threads stop running and execution should return to priority 6 (lock holder)

[Quantum Leaps]

It seems that this problem was introduced in QP 7.1.0, so the affected releases are: QP 7.1.0 .. 7.2.0 (both QP/C and QP/C++).
