> Compared to the LLVM compiler, where the option already exists, the implementation in the GCC compiler has some improvements and advantages:

> Complex uses of gotos and case labels are properly handled and should not report any false positive or false negatives.

> C++ temporaries are sanitized.

This is a nice improvement -- I've seen escapes happen here.
