Bug#95840 Compilation with g++ 9.1.1 fails was marked as a duplicate.
Description: gcc 9.1.1 reports new warnings (comparison of signed and unsigned) which are treated as errors in debug builds. E.g. /export/home/tmp/clones/bug_29169678/router/src/http/src/kdf_pbkdf2.cc: In static member function ‘static std::vector<unsigned char> Pbkdf2::salt()’: /export/home/tmp/clones/bug_29169678/router/src/http/src/kdf_pbkdf2.cc:53:18: error: comparison of integer expressions of different signedness: ‘std::vector<unsigned char>::size_type’ {aka ‘long unsigned int’} and ‘int’ [-Werror=sign-compare] 53 | if (out.size() > std::numeric_limits<int>::max()) { | ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1plus: all warnings being treated as errors How to repeat: Build with gcc 9.1.1 and debug Suggested fix: Add explicit casts as necessary.
