Maybe you are being too specific in your example, and thus I am being nitpicky rather than helpful, but wouldn't that be caught by a static analyzer?

- BudVVeezer 12y agoI just tried the following simple example: #include <string.h> struct S { int i; char c; int j; }; void f(void) { struct S s1 = { 0, 0, 0 }, s2 = { 0, 0, 0 }; memcpy(&s1, &s2, 9); } int main(void) { f(); return 0; } MSVC, Clang, and PC-Lint are all silent on the code (which is reasonable behavior since it's impossible to glean programmer intent from that snippet -- maybe the programmer really only wants the first nine bytes!). (Btw, yes, I am using the analyzer features for MSVC and Clang, not just relying on high warning levels.)
