-Subject: [PATCH 14/14] liblzma: Avoid memcpy(NULL, foo, 0) because it is
- undefined behavior.
-
-I should have always known this but I didn't. Here is an example
-as a reminder to myself:
-
-    int mycopy(void *dest, void *src, size_t n)
-    {
-        memcpy(dest, src, n);
-        return dest == NULL;
-    }
-
-In the example, a compiler may assume that dest != NULL because
-passing NULL to memcpy() would be undefined behavior. Testing
-with GCC 8.2.1, mycopy(NULL, NULL, 0) returns 1 with -O0 and -O1.
-With -O2 the return value is 0 because the compiler infers that
-dest cannot be NULL because it was already used with memcpy()
-and thus the test for NULL gets optimized out.
-
-In liblzma, if a null-pointer was passed to memcpy(), there were
-no checks for NULL *after* the memcpy() call, so I cautiously
-suspect that it shouldn't have caused bad behavior in practice,
-but it's hard to be sure, and the problematic cases had to be
-fixed anyway.
-
-Thanks to Jeffrey Walton.
