-Replace do_{_if_(condition)_{_..._continute;_}_}while_{false}; with
for(;;)_{_if_(condition)_{...}_else{break;_}_} for an infinite loop
with a break logic to handle waiting concurrent gc finish during
continuation mounting. compiler might generate wrong logic for
do_while infinite loop.
-fix small hole during mounting synchronization with concurrent
scanning(for the case concurrent scanning start just before resetting
pendingmount flag-before reading the value of state for atomic update)
- new assertion check for catching issue earlier.
