Cppcheck-1.67

Cppcheck-1.67 has been released.

General changes:

• Library files have now a 'format' attribute. Format version 1 is assumed by default
• Cppcheck does no longer abort checking if unhandled characters (Non-ASCII) are found

New checks:

• Check for unused return values
• Detect shift by too many bits, signed integer overflow and dangerous sign conversion
• Recommend usage of expm1(), log1p(), erfc()
• Division by sizeof() as parameter to memset/memcpy/memmove/etc. as they expect a size in bytes
• Several new va_arg related checks:
  -- Wrong parameter passed to va_start()
  -- Reference passed to va_start()
  -- Missing va_end()
  -- Using va_list before it is opened
  -- Subsequent calls to va_start/va_copy()
• Initialization by itself in initializer list
• Dead pointer usage when pointer alias local variable that has gone out of scope

Improvements:

• Support uniform initialization syntax (C++11)
• Much improvements to value flow analysis
• Improved AST creation (support placement new, C++-style casts, templates, operator new[], ...)
• Improved lambda support
• Support GCC extension attriute((used)) and MSVC extension __declspec(property)
• Better support for static member variables, inherited variables and namespaces
• Improved typedef support where multiple variables are declared at once
• Avoid checking code multiple times by calculating a checksum. Duplicate preprocessor configurations are eliminated by this.
• Support C++03/C 'auto' keyword
• HTML report: display 'verbose' message using clickable expandable divs

Additionally, lots of false positives and bugs have been fixed and several existing checks have been improved.
