given that the expectation is this will be read into a buffer and both `size` and `nmemb` are `size_t` I'm not concerned with overflow. Normally `size_t` is `uint64`, meaning you'd need to try and read 2^64 bytes bytes before it was an issue. https://github.com/llvm/llvm-project/pull/168931 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
