Turn on strncat-size warning implemented a while ago.
Warns on anti-patterns/typos in the 'size' argument to strncat. The
correct size argument should look like the following:
- strncat(dst, src, sizeof(dst) - strlen(dest) - 1);
We warn on:
- sizeof(dst)
- sizeof(src)
- sizeof(dst) - strlen(dst)
- sizeof(src) - anything
(This has been implemented in void Sema::CheckStrncatArguments().)
