By setting Options::forceDebuggerBytecodeGeneration() = true to force the BytecodeGenerator to generate debugger friendly bytecode, the JSC stress tests now fails as follows: ** The following JSC

regress/script-tests/deltablue-varargs.js.no-cjit-validate-phases Results for JSC stress tests: 89 failures found. I haven't investigated the rest of the failures yet, but at least the constant-count.js case is a regression.
