I have uploaded a fixed wget for focal, verified that it only loads the config file once.
** Description changed: - "double free" error is seen when using curl utility. Error is from - libcrypto.so which is part of the OpenSSL package. This happens only - when OpenSSL is configured to use a dynamic engine. + [Impact] + openssl config file is being loaded twice, causing engines to be loaded twice if specified therein, causing double free errors and other strange behavior. + + [Test plan] + Run the command of the package being tested in + + gdb -ex "break CONF_modules_load_file" -ex "run" --args + + and make sure it only breaks one. + + [Where problems could occur] + + wget: This is an upstream change that changes initialization and is in + use in later releases. Since it mostly removes an unneeded call to the + load file function, a regression could be a config file being ignored, + but it seems unlikely given the use in later releases + + [Original bug report] + "double free" error is seen when using curl utility.
