Per bug #76651 these changes do not appear to work correctly in
some cases. As no immediate fix seems to be forthcoming, I'm
reverting these changes.
Revert "Fixed invalid free introduced by d6e81f0bfd (avoid keeping "invalid" pointer)"
This reverts commit 11507c0e1b.
Revert "Fix mysqlnd build without openssl"
This reverts commit 6c9db02ff7.
Revert "Fix VC compilation as variable size array is not supported"
This reverts commit f96df64cb2.
Revert "Fix MySQL 8 auth"
This reverts commit d6e81f0bfd.
The reason was that after the big refactoring of mysqlnd at the end of
last year code that is initializing the error_info structure in the
result set was not added. It existed already for connections and PS.
The code that segfaults is hit only with MariaDB because MariaDB sends
full metadata about the EXPLAIN query + EOF packet and only then it sends
an error packet. MySQL doesn't do that but sends directly an error which
is caught (by different code path). As errors during execution (which means
after sending meta) are pretty rare there was no test case of MySQL to
catch it.
