With the changes in JDK-8319883 additional stringop-overflow warnings are produced with GCC 13.2.0, this time for linux-x64-zero (fastdebug). The warnings are related to GCC thinking JavaThread:current (and Thread::current) may return nullptr where in fact they can't. I tried several ways to convince GCC about this fact but in the end failed.
