I am running the libCom tests on vxWorks to see if I broke anything (implementing new atomicCompareAndSwap). I found that some tests were failing (even crashing) already with the current 7.0 version (commit :1cacd05).

Listing the faults here (full log attached)
Note the crash of "await" in the first test!
(Sometimes it prints instead: (await): Unhandled C++ exception resulted in call to terminate )
It dies taking an uninitialized semaphore.

After finishing,  ("Reached mainExit") the test program hangs instead of returning to the vxWorks shell.
If started from a vxWorks startup script, it ends in a loop. printing over and over again:
-> 
Shell task 'tShell0' restarted...
