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.
Just a clarification... This -DNDEBUG option addition to compile lines
will likely result in a small reduction in code size, and a small performance
improvement on Linux and Windows, perhaps hard to measure.
I will verify that a JDK7 image built this way still serves as a basic
BOOT JDK successfully.
The product builds (optimized non-debug builds) should not rely on
native code standard assert() uses to do 'anything'.
