------- Comment #2 from felix-gcc at fefe dot de 2008-03-14 19:58 ------- I am aware of -Wconversion, but I am not interested in ALL conversion truncations. Truncation happens to be a security issue in a few cases, in many other cases it would just be a regular bug. My suggestions aims to isolate the security relevant cases, for the rest we have -Wconversion.
If the size_t given to memcpy is truncated, that does not overwrite a buffer. But if the size_t given to malloc is truncated, that is a pretty surefire way to find a security issue. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35592
