In several places in HotSpot, the C++ code has Undefined Behaviour. This includes null pointer dereferences and accesses to objects outside their lifetimes.
While many of these bugs are fixed are fixed in later releases, the changes are intrusive and extensive, and arguably too much for a stable (not to say vintage) project like OpenJDK 8. Therefore, in order to allow 8u to build on new versions of GCC we should use the following build-time options if they are available:
-fno-lifetime-dse -fno-delete-null-pointer-checks
