RESOLVED FIXED 134928
ScriptExecutable::forEachCodeBlock can dereference null CodeBlocks

Summary ScriptExecutable::forEachCodeBlock can dereference null CodeBlocks
Mark Hahnenberg
Reported 2014-07-15 10:38:22 PDT
Executable::forEachCodeBlock doesn't check for null CodeBlocks in the ProgramExecutable and EvalExecutable cases, so if the CodeBlock has been cleared from either of these Executables we'll crash when dereferencing null inside whatever functor was passed.
