It was found that compiling src/java.base/share/native/libjava/Bits.c using normal (-O2) optimization instead of high (-O3) resolved the immediate problem. The concern however is that there is an underlying pattern in the optimized compiled code which might manifest itself elsewhere. It would be better to examine the problem in detail in order to find the root cause and hopefully a better solution.
