6855551: java -Xrunhprof crashes when running with classes compiled with targed=7
   Related to 6855180, assert logic could get segv, investigation found next one.

6858127: Missing -DNDEBUG on Linux and Windows native code compiles
   The C/C++ macro NDEBUG when defined turns assert() macros into nothingness.
   These assert() macros are for debug builds, not product builds, when
   an assert fails, it prints out information and typically exits the process.
